Acrylic RPD Clinical Sequence Template

Acrylic RPD Clinical Sequence — Form 26

Chairside Form 26 for an acrylic-based removable partial denture — mucosa-supported, with wrought-wire clasps added after the acrylic is processed. Use Sequence A when the vertical dimension is unchanged, and Sequence B when you are increasing it. Material selection, the decision criteria and the impression tables live in Partial Denture Template; this sheet is the single-material, paste-and-go version.

Two signatures required

Form 26 is the reconstructive phase. You need two signatures — the prosth specialist and the clinic coordinators. No aesthetic work goes on this form.

When acrylic is the right choice

Acrylic suits a mouth that is still changing. Choose it when the dentition is changing, when the prognosis of one or more teeth is questionable, when further extractions are likely, when the periodontal condition is not yet stable, or when the patient needs teeth while treatment runs over several months. It is easy to modify and easy to add teeth to, it is cheaper and simpler to make than cobalt-chromium, and it is the sensible interim prosthesis while you manage emergencies, caries, periodontal disease and the extraction decisions that follow. An immediate partial is made before the extraction and inserted straight afterwards, which stabilises the clot and holds the adjacent and opposing teeth in position.

An acrylic denture is not automatically a temporary one. A well-made acrylic denture can be definitive, although it covers more tissue than a cobalt-chromium framework does.

The limitations are that it is bulkier, it fractures more readily, and it retains less well and lasts less well than cast metal. Where a severe loss of vertical dimension leaves too little prosthetic space for an adequate thickness of acrylic, a metal framework is required instead — reassess before committing to acrylic.

How this pathway differs from cobalt-chromium

There is no framework, so there is no framework fabrication and no framework try-in appointment. The master cast is not duplicated, surveyed or cast, and the maxillo-mandibular relationship is recorded on a record base and wax rim built on the master cast rather than on a framework. Mouth preparation is the control phase only: the second, biomechanical stage — rest seats, guide planes, height-of-contour recontouring, survey crowns — exists to seat a metal framework accurately, and an acrylic partial is tissue-supported. It is not zero tooth contact, though; acrylic partials still carry wrought-wire clasps engaging a 0.75 mm undercut and occasionally a simple rest. The clasps are bent from drawn stainless-steel wire and embedded in the acrylic after processing, not cast into a framework, which is why they can be adjusted by bending. The laboratory prescription is correspondingly simpler: master cast, bite registration, clasp positions, teeth to be replaced, shade.

A straightforward tooth-supported case can run in four appointments. Appointments 3 and 4 are the two that drop out, and the criteria for each are in Partial Denture Template.

Appointment 1 — Primary impressions and records

Complete the control phase first. The perio, endo, restorative and surgical work has to be finished before the impression you will work from is taken, because the cast records the mouth as it was on the day. If any of that work happens afterwards and it changes the relevant teeth or the ridge, take the impression again.

Take an alginate impression in a stock tray, modified as needed — heat it to widen it, add putty to extend it, or use green-stick compound or periphery wax. Modify the tray if it contacts the ridge or is too short. Accept the impression only when the relevant teeth and the saddles are captured; it also gives you the basis for a preliminary survey, even when the plan is a simple wrought-wire clasp. Take a bite registration on every case — it is quick, and you can decide afterwards whether you use it.

Before you write the prescription, choose the definitive impression material, because it decides the tray design.

Impression material	Tray	Spacer
Alginate	Perforated	3 mm
PVS	Non-perforated	2 mm
Polyether	Non-perforated	2 mm

The spacer is wax laid on the stone cast before the tray is made, and it is what leaves room for the impression material. Tissue stops are extensions that contact selected teeth and stop the tray sinking into the tissues — worth asking for while you are still building up experience with tray pressure.

Between appointments — laboratory: pour the study casts in type 3 gypsum and fabricate the special tray.

Appointment 2 — Special tray try-in and definitive impression

Try the tray in first: seat it and check the gross extension, the seating, any interference and any sharp edges. Then check it in function — manipulate the cheeks and lips, and have the patient move the tongue. Trim wherever the tray is displaced, then repeat the movements and reassess. A tongue movement to the left that lifts the tray means the right lingual flange needs trimming, and the same logic applies on the other side. Small movement is acceptable; gross movement is not.

Decide whether to border-mould. Border-mould when the functional extension of the base matters: a Kennedy I or II free-end saddle, a long Kennedy IV, a large tissue-supported saddle, or a posterior maxillary extension running into functionally relevant soft tissue.

Block out the undercuts before you load anything. The risk areas are black triangles and open embrasures, gingival recession, tipped teeth, undercuts beneath a bridge or pontic, and mobile or periodontally compromised teeth. Periphery wax is the easiest material; a light-cure gingival barrier, PTFE tape, Oraseal or a temporary restorative material all work. Block out from the buccal so that the lingual extension is preserved, and aim only to stop material passing buccally to lingually and locking between the surfaces — the blockout does not have to encircle the tooth. How much you need depends on the material: alginate generally flexes out, heavy-body PVS should be blocked interproximally, and polyether should always be blocked out when undercuts are present.

A locked polyether impression is a genuine emergency

Set polyether locks into undercuts. Getting one out can mean removing a tooth with the impression, sectioning the tray, or cutting the material while it is still in the mouth, with a real risk of injuring the lips and soft tissues. Block out properly before you load it.

Apply tray adhesive. PVS is the usual choice, alginate is acceptable, and polyether is used rarely. At OCHWA the PVS is Imprint 4 in heavy body, regular body and light body. Medium body alone, heavy plus light, or medium plus light are all defensible combinations — this is clinician preference, not a rule. Do not mix generations of the same product, because the setting times may not match.

Use light body where the detail matters: rest seats, guide planes, prepared tooth surfaces, and lingual or palatal plate contact areas. On a routine acrylic denture light body is not always necessary, and where heavy body has dragged, light body can fill the defect.

Judge the impression yourself before you show it to anyone. On a tooth-supported bounded saddle you need the saddle anatomy, the path-of-insertion information and the relevant tooth surfaces. On a free-end or long saddle you need the abutment teeth, the whole denture-bearing area, the buccal and lingual extension, the retromolar pad or tuberosity, and the functional peripheral form. Judge a defect by where it falls: a drag between two teeth that no part of the denture will occupy may be perfectly acceptable, while a defect in the retromolar pad or the buccal shelf is not.

Between appointments — laboratory: pour the master cast, and make a record base and wax rim if the next appointment needs one.

Appointment 3 — Maxillo-mandibular relationship

Only when the case needs one. A recorded MMR on a base and rim is essential for a Kennedy I or II free-end saddle, a long Kennedy IV, unstable occlusal stops, or any change in the vertical dimension. It is not essential for a Kennedy III that hand-articulates, and that case goes straight from Appointment 2 to the tooth try-in or the insertion.

The question is not whether the patient can bite together — it is whether the technician can articulate these casts predictably. The patient’s joints and muscles stabilise a free-end case in the mouth; rigid casts on a bench have nothing holding them.

Test it: put the casts together and see whether they are stable or whether they rock and slide. Three stable contacts — one in each posterior region and one anterior — may be enough, and four are better. Compare the articulating-paper marks on the articulator against the marks in the mouth. Where they disagree, suspect an inaccurate bite record, incorrect articulation, compression of the free-end tissues or the periodontal ligament, bubbles in the bite material, stone caught between the occlusal surfaces, or untrimmed interproximal extensions on the record.

Scanning the bite

A digital interocclusal record is more predictable with a short bounded saddle, stable teeth, good access and moisture control, reliable occlusal landmarks and minimal tissue displacement. It is more challenging with a long edentulous span, a free-end saddle, mobile or displaceable tissues, a functional border to record, limited access or difficult tongue and cheek control, and few stable occlusal landmarks. The scan can look beautiful and the bite can still be wrong, so validate it clinically in the scanner’s contact-only mode. If you go digital, stay digital rather than alternating between scans, printed casts and conventional records.

This reverses what an earlier version of this sheet said. Free-end saddles are the hard case for a digital record, not the indication for one.

Try the record base and wax rim in and check the adaptation and stability. Set the vertical dimension by subtracting the freeway space from the resting vertical dimension and check it with the closest speaking space. Take the facebow and a protrusive record. Mark the midline, the canine lines, the smile line and the labial contour on the rim — the rim is the technician’s blueprint for where the teeth go. Select the shade and the mould, and send a photograph of the shade tab in the mouth.

Between appointments — laboratory: cross-mount the casts and set the teeth on the same hard base.

Appointment 4 — Tooth try-in

Only when the case needs one. A try-in is worth the appointment when several teeth are being replaced, when the case is in the aesthetic zone, when the tooth position or the occlusion is uncertain, when the vertical dimension has been altered, or when you are simply not sure. Go straight to a direct finish only for a single straightforward tooth with good neighbouring references, a stable occlusion and minimal aesthetic risk — and if you do, the shade, the mould and the shade photograph have to be right the first time, because there is no later chance to correct them.

Assess the tooth position, the aesthetics, the phonetics, the occlusion, the retention and stability, the vertical dimension where it is relevant, and the patient’s acceptance. Check the vertical dimension with shim stock: the patient should hold the shim between the same natural teeth with and without the denture in. If contact is lost with the denture in, the denture has opened the bite and needs adjusting before processing. Move teeth rather than grinding them, and document the patient’s approval.

Between appointments — laboratory: process the denture and add the wrought-wire clasps after processing.

Appointment 5 — Insertion

Do not force the denture in. Work out the path of insertion first — posterior to anterior, right to left, or seating simultaneously — then look for the first point of contact and adjust conservatively. Adjust the rigid acrylic interface before you touch the clasp. A tight acrylic denture is usually tight because acrylic or wax sits in the interproximal areas near the clasps, and adjusting the clasp when the acrylic is the obstruction is the common error. Do not over-trim the embrasures either, or the patient gets food packing instead.

Inspect the base before it goes in. Send it back to the lab if there are voids or porosity; remove nodules and sharp projections chairside; trim overextensions and round the sharp edges.

Then check the seated denture: retention, stability and base extension; the occlusion with articulating paper; the vertical dimension, which processing can shift; the appearance; and that nothing impinges on the soft tissues. Adjust the wrought-wire clasp engagement by bending the wire, without over-tightening it. If the saddle adaptation is poor, reline it — and take the bite registration before the pickup impression.

Have the patient insert and remove the denture themselves before they leave, and give care, cleaning and adaptation instructions.

Appointment 6 — Review, about two weeks

Assess how the patient has adapted and deal with the complaints. Confirm the true pressure points here rather than over-adjusting at insertion: fit checker or light body will show them, and perforations mark strong contact. Trim gradually with an acrylic bur in a straight handpiece. Re-check the clasp retention, and remember that teeth can be added later if further extractions happen.

Sequence B — acrylic RPD with an increase in vertical dimension

Appointment	What happens	Laboratory afterwards
1	Primary impressions and records	Study casts; diagnostic base and rim
2	Jaw relations at the new vertical dimension	Mount at the new OVD; diagnostic wax-up
3	Wax-up review and stabilising the new vertical dimension	Special tray
4	Special tray try-in and definitive impression at the new OVD	New master cast; record base and rim
5	Maxillo-mandibular relationship at the new OVD	Cross-mount; set the teeth
6	Tooth try-in	Process; add the wrought-wire clasps
7	Insertion	—
8	Review, about two weeks	—

The skeleton is Sequence A. What changes is that the new vertical dimension is established and stabilised before the definitive impression, and the impression is taken again once the teeth have changed shape.

Appointment 1 — Primary impressions and records

As in Sequence A. Here the diagnostic base and rim is effectively always needed, because it is what carries the new vertical dimension.

Appointment 2 — Jaw relations at the new vertical dimension

Establish the target increased vertical dimension on the wax rim rather than simply recording the existing intercuspal position. Use the extraoral references from the base of the nose to the chin, subtract the freeway space from the resting vertical dimension, and confirm with phonetics and the closest speaking space. Take the facebow and the jaw relation at the new vertical dimension. Select the shade and mould, and mark the landmarks.

Between appointments — laboratory: mount the casts at the new vertical dimension and wax up to it.

Appointment 3 — Wax-up review and stabilising the new vertical dimension

Review the wax-up at the new vertical dimension and confirm the occlusal plane. Finalise the clasp positions, the teeth to be replaced and the shade.

Then place the composite build-ups and restorations to the planned vertical dimension. Verify comfort, phonetics and occlusion, and allow an adaptation period before going further. A heavily worn dentition — which is the usual reason for raising the vertical dimension in the first place — often warrants a prosthodontic referral, so assess the complexity before committing. A large number of build-ups may well take more than one appointment.

If a survey crown is part of the plan

Take the diagnostic MMR first to establish the new vertical dimension. Have the crown waxed up at that new dimension before preparing the tooth, so that minimal occlusal reduction is needed. After preparing and taking the secondary impression, send another MMR so the lab can articulate the casts for the crown. Only once the crown is cemented do you take the final MMR and impression for the denture. The crown itself runs on PFM Survey Crown Template and adds its own appointments here.

Between appointments — laboratory: make the special tray.

Appointment 4 — Special tray try-in and definitive impression at the new vertical dimension

The teeth are no longer the shape the diagnostic cast recorded, so take a new impression that reflects the built-up teeth and the cemented crowns. Tray try-in, border moulding, blockout, material choice and impression assessment are all as in Sequence A, Appointment 2.

Between appointments — laboratory: pour a new master cast, and make a record base and wax rim at the new vertical dimension.

Appointments 5 to 8 — Rejoin Sequence A

The maxillo-mandibular relationship, the tooth try-in, the insertion and the review run as in Sequence A. Every record from here is taken at the new vertical dimension, and the finished acrylic denture is built to it — the denture can itself carry the interim vertical dimension. Provisional composite build-ups can be replaced with definitive restorations later if that was the plan.

Example laboratory prescriptions

What every slip carries before the job-specific part

The date, the patient details and the return date — enter the return date at least one day before the patient’s appointment. Then the job summary, the models required, the materials requested, the construction details, any enclosed design drawing, decontamination confirmation, the tutor’s signature and D-number, and your contact details. Register the job on LabMagic, and submit the Removable Prosthodontics and Laboratory Stages (Progress Monitor) with the slip — every stage on it is signed before the next one starts. The slip itself is a Titanium eForm; only the dates are editable on screen, so print it to mark the odontogram and write the requirements.

Turnaround runs to about 15 days for some prosthetic work, and a job returned for correction doubles that — so get the instruction right the first time.

What an acrylic denture slip has to detail, across the whole case: the master cast, the bite registration, the clasp positions, the teeth being replaced, and the tooth shade. That is the whole list — there is no framework design to describe, no major connector, no rest locations. The clasps are wrought wire added after processing, so the clasp instruction belongs on the processing slip rather than on any earlier one.

After Appointment 1 — study casts and special tray

Dear Lab,

Please pour up the maxillary and mandibular alginate impressions for study models in type 3 gypsum, and articulate them using the enclosed bite registration.

Please fabricate upper and lower special trays as follows: maxillary perforated special tray with 3 mm spacer for an alginate impression; mandibular non-perforated special tray with 2 mm spacer for a PVS impression, with tissue stops.

Thank you.

The tray sentence is the lecture’s own worked example (L5 RPD Hindawi). Name the arch, the material, perforated or not, the spacer, whether tissue stops are wanted, and what the impression is for. “Dear Lab, please make special tray” gives you no standing to criticise the design that comes back.

After Appointment 2 — master cast, and a record base if the case needs one

Dear Lab,

Please bead, box and pour the enclosed definitive impression as the master cast.

This is an acrylic partial denture replacing [teeth __], with wrought-wire clasps on [teeth __]. Shade [__].

Please check whether the casts articulate predictably against the enclosed bite registration. If they do not, please fabricate an acrylic base with a wax rim for the maxillo-mandibular record.

Thank you.

Ask for an “acrylic base for wax rim (MMR)” in those words. A slip that says only “wax rim” comes back as a wax rim with no rigid base, and it will not hold a record.

After Appointment 3 — mounting and tooth setting

Dear Lab,

Please cross-mount the casts using the enclosed facebow and centric relation record, and set up the teeth on the same hard base for a wax try-in.

Teeth to be replaced: [__]. Shade [__], mould [__].

The midline, canine lines, smile line and labial contour are marked on the rim. Please set the teeth to the marked positions, with [__] mm overjet and [__] mm overbite.

Full-face photographs with the rim in the mouth, smiling and at rest, are attached.

Thank you.

After Appointment 4 — processing

Dear Lab,

The wax try-in was approved by the patient [or: approved with the following changes: __].

Please finalise, process, polymerise and finish the denture, and add the wrought-wire clasps on [teeth __] after processing.

Please maintain the waxed labial flange contour through processing — it is carrying the lip support.

Thank you.

Where this wording comes from

The special-tray example is quoted from L5 RPD Hindawi. Everything else here is built to the field lists in L9 Clinical Sequence (“Laboratory Requirements by Denture Type”), Laboratory Prescriptions (a complete-denture note, so its rim dimensions do not transfer) and the OCHWA slip checklist in Treatment Planning session 1. The vault holds no worked RPD prescription wording for any stage other than the special tray, so treat these as models to adapt, not as house-approved text.
