W. Wassell, D. Barker, and J. G. Steele - **Publication:** *Practice* - **Date:** 13 July 2002 # TRY-IN PROCEDURE ## IDEAL CROWN - Easily seated - Stable - Accurate occlusal contact - Adequate proximal contacts - Accurate marginal fit - Aesthetic An ideal crown should exhibit the following characteristics: - Easily seated - Stable - Accurate occlusal contact - Adequate proximal contacts - Accurate marginal fit - Aesthetic # TRY-IN PROCEDURE ## Evaluation: Seating, fitting, contact points Systematic approach 1. Evaluation of the crown on the **die** 2. Seating the crown on the **prepared tooth** 3. Assessment of the seated crown The evaluation process for seating, fitting, and contact points requires a systematic approach: 1. Evaluation of the crown on the **die** 2. Seating the crown on the **prepared tooth** 3. Assessment of the seated crown # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE ### Aims: - Detection of fabrication errors (laboratory related) prior to the clinical appointment - Save critical chair time - Anticipation of problems before clinical appointment - Consider good lighting and magnification - In case of problem, consult with the dental laboratory   #### Objectives of Die Evaluation - Detection of fabrication errors (laboratory related) prior to the clinical appointment - Save critical chair time - Anticipation of problems before the clinical appointment - Utilize good lighting and magnification during inspection - Consult with the dental laboratory in case of identified problems # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE <img src="image1.jpg" alt="A dental crown with a screw attached, labeled 'Screw Retained (Occlusal Screw)'"> <img src="image2.jpg" alt="A hand holding a small dental crown"> <img src="image3.jpg" alt="A hand placing a dental crown on a model"> <img src="image4.jpg" alt="A dental model with multiple crowns">     Visual inspection includes checking various restoration types and mounting methods, such as screw-retained (occlusal screw) components and the manual placement of the crown on the laboratory model. # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE Assess the die and opposing model - Poor pouring - Overtrimming - Fracture - Scratches - Wear  Inspect the models for the following defects: - Poor pouring - Overtrimming - Fracture - Scratches - Wear # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE ### Assess the die and opposing model - Poor pouring - Overtrimming - Fracture - Scratches - Wear <img src="https://i.imgur.com/3j0Z1zW.png" alt="Six images of dental crowns labeled Crown 1 to Crown 6, each showing different conditions on a die model." />   Verify the integrity of the die and opposing model, checking for: - Poor pouring - Overtrimming - Fracture - Scratches - Wear # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE **Internal surface:** - Casting problems: air bubbles - Casting nodules or blebs - Ideally, the casting should touch the die at the margins only <img src="image_of_die_spacer.png" alt="Close-up of a die spacer being held by fingers" /> Die spacer  #### Internal Surface Inspection - **Casting problems:** Check for air bubbles. - **Surface irregularities:** Identify casting nodules or blebs. - **Seating principles:** Ideally, the casting should touch the die at the margins only. - **Die Spacer:** Ensure appropriate application to accommodate the cement lute. # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE **Overall fit and resistance:** - Looseness - Excessive gap - Proximal contact areas **Marginal fit:** - Open margins - Overhangs or underextensions #### Fit and Resistance - Check for looseness or excessive gaps. - Evaluate proximal contact areas. #### Marginal Integrity - Identify open margins. - Check for overhangs or underextensions. # Try-In Table 1. Check list of laboratory errors affecting marginal fit | Error | Cause | Remedy | | :--- | :--- | :--- | | Tight proximal contacts | Imprecise die location or abrasion of the adjacent stone contact points | Check for displacement of the dies when the crown is seated on the working cast. Identify tight contact by interposing articulating paper, grind and polish | | Casting blebs on fit surface | Air bubbles trapped during investment | Identify under magnification and remove with small round bur | | Over-extended crown margins | Poor impression, poor die trimming, surplus untrimmed wax or porcelain | Trim from axial surface (Fig. 1) and polish – consider returning crown to lab | | Under-extended crown margins | Poor impression, poor die trimming, difficulty identifying finish line | If under-extension obvious and impression satisfactory have crown remade. Alternatively retake impression | | Damaged dies | Finish line chipped because of careless handling or abraded when casting reseated with blebs or overextended margins | Always try and determine why the die is damaged. If the crown does not fit after adjusting blebs or over-extended margins return it to laboratory | | No die spacer (Space needed to accommodate cement lute) | Technician not aware of technique or forgot to apply | Lack of spacer results in a tightly fitting crown which may not seat during try in and may 'lift' further after cementation |  #### Laboratory Error Checklist | Error | Cause | Remedy | | :--- | :--- | :--- | | **Tight proximal contacts** | Imprecise die location or abrasion of stone contact points | Check for die displacement; identify with articulating paper; grind and polish. | | **Casting blebs on fit surface** | Air bubbles trapped during investment | Identify under magnification and remove with small round bur. | | **Over-extended margins** | Poor impression, trimming, or surplus wax/porcelain | Trim from axial surface and polish; consider returning to lab. | | **Under-extended margins** | Poor impression or difficulty identifying finish line | If obvious, have crown remade. Alternatively, retake impression. | | **Damaged dies** | Chipped finish line or abrasion from reseating faulty castings | Determine cause of damage. If fit fails after adjusting blebs, return to lab. | | **No die spacer** | Technician error or lack of awareness | Results in tight fit; crown may not seat or may 'lift' after cementation. | # TRY-IN PROCEDURE ## EVALUATION OF CROWN ON THE DIE ### External surface - Appearance (restoration design) - Contour - Shade - Rough or smooth (polished) ### Occlusion (articulator) - Centric contacts - Eccentric contacts - Interferences <img src="image.png" alt="Close-up image of a dental crown on a die, showing the external surface and occlusion details." />  Evaluate the following external characteristics: - Appearance and restoration design - Contour - Shade - Surface texture (rough vs. polished) Verify the following on the articulator: - Centric contacts - Eccentric contacts - Interferences # TRY-IN PROCEDURE ## SEATING THE CROWN - The crown should seat on the prepared tooth without forcing - If it is not seating, possible causes may involve: The crown should seat on the prepared tooth without forcing. If resistance is encountered, investigate potential causes. # TRY-IN PROCEDURE ## SEATING THE CROWN - The crown should seat on the prepared tooth without forcing - If it is not seating, possible causes may involve: - Single crown - Proximal contacts - Internal fit - Inaccurate margins/ over extensions - Retained temporary cements - Trapped gingival tissue  The crown should seat without forcing. Potential causes for seating failure include: - Proximal contact issues - Internal fit discrepancies - Inaccurate margins or over-extensions - Retained temporary cements - Trapped gingival tissue # TRY-IN PROCEDURE ## SEATING THE CROWN - The crown should seat on the prepared tooth without forcing - If not, possible causes may involve: ### Single crown - Proximal contacts - Internal fit - Inaccurate margins/ over extensions - Retained temporary cements - Trapped gingival tissue ### FPD - Same as for single crown - Tissue contact under pontics - Location and shape of connectors #### Troubleshooting Seating Issues **Single Crowns:** - Proximal contacts - Internal fit - Inaccurate margins / over-extensions - Retained temporary cements - Trapped gingival tissue **Fixed Partial Dentures (FPD):** - All factors listed for single crowns - Tissue contact under pontics - Location and shape of connectors # TRY-IN PROCEDURE ## SEATING THE CROWN Remove the provisional restoration - Excavator, sickle probe - Hemostat, Backhaus forceps, pliers - Crown remover: - Back-action crown remover - Automatic crown remover - Richwill crown remover         #### Instruments for Removal - Excavator, sickle probe - Hemostat, Backhaus forceps, pliers #### Crown Removers - Back-action crown remover - Automatic crown remover - Richwill crown remover # TRY-IN PROCEDURE ## SEATING THE CROWN Remove the provisional restoration - Excavator, sickle probe - Hemostat, Backhaus forceps, pliers - Crown remover: - Back-action crown remover - Automatic crown remover - Richwill crown remover  The provisional restoration is removed using tools such as excavators, probes, hemostats, or specialized crown removers (back-action, automatic, or Richwill). # TRY-IN PROCEDURE ## SEATING THE CROWN ### Proximal contacts - Assess tightness with dental floss - There should be some tightness but not too difficult - Articulating paper (20 μm), marking liquid (Accufilm), spays (occlude) - The shim stock (8 μm) should just pass through the contact - Minor adjustment at a time - If the contacts are open, return to the laboratory for material addition   #### Assessment and Adjustment - Assess tightness with dental floss; there should be some resistance but not excessive. - Use articulating paper (20 μm), marking liquid (Accufilm), or sprays (Occlude) to identify contacts. - **Shim stock (8 μm):** Should just pass through the contact. - Perform minor adjustments incrementally. - **Open contacts:** If contacts are missing, return the crown to the laboratory for material addition.    *(Page intentionally left blank or contains no unique text content)* # TRY-IN PROCEDURE ## SEATING THE CROWN **Proximal contacts** Should be at the same location to the natural proximal contacts <img> two images side by side, one showing a dental crown on a model tooth with a red shaded area indicating the contact point, and the other showing a dental crown on a metal holder with a red marking on the occlusal surface.   #### Contact Location Proximal contacts should be positioned in the same location as the natural proximal contacts. Use marking media to visualize the contact point on the restoration. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Internal fit - The restoration should seat completely without interference of the occlusal or axial surfaces - The fitting surface should be checked and adjusted accordingly - Disclosing medium (Fit Checker, LB impression material) - Spraying thin layer of aerosol indicator (Occlude) - The relief can be achieved with a diamond bur   #### Internal Surface Evaluation - The restoration must seat completely without interference from occlusal or axial surfaces. - **Detection Methods:** - Disclosing medium (Fit Checker, light-body impression material) - Aerosol indicators (Occlude spray) - **Adjustment:** High spots can be relieved using a diamond bur. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Internal fit Fit Checker application - Penetrated areas of the medium indicate high spots - Can be adjusted accordingly   #### Interpreting Fit Checker - Areas where the medium is penetrated (thinned out) indicate high spots or points of interference. - These areas should be adjusted to ensure full seating. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Internal fit If crown fits the model well but does not seat in the mouth, consider problems with impression Caused by: - Early impression removal - Distortion of impression - Latex contamination Take a new impression  #### Clinical vs. Laboratory Fit Discrepancies If the crown fits the model well but fails to seat in the mouth, consider impression-related issues: - Early impression removal - Distortion of the impression - Latex contamination **Action:** A new impression is required. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Marginal fit - Should be as accurate as possible - Poor marginal adaptation: - Gap (100 microns is the borderline for acceptability, and can be felt by a probe) - Overhang - Under extension - Ledge #### Marginal Adaptation Marginal fit should be as accurate as possible. Common poor adaptation issues include: - **Gap:** A gap of 100 microns is the borderline for acceptability (detectable by probe). - **Overhang** - **Under-extension** - **Ledge** # TRY-IN PROCEDURE ## SEATING THE CROWN ### Marginal fit | | | | | | | :--- | :--- | :--- | :--- | :--- | | <img src="image1.png" alt="Ideal marginal fit"> | <img src="image2.png" alt="Overextended marginal fit"> | <img src="image3.png" alt="Underextended marginal fit"> | <img src="image4.png" alt="Overhang marginal fit"> | <img src="image5.png" alt="Open margin marginal fit"> | | Ideal | Overextended | Underextended | Overhang | Open margin |  #### Visual Classification of Margins - **Ideal:** Perfect adaptation to the finish line. - **Overextended:** Material extends beyond the finish line. - **Underextended:** Material stops short of the finish line. - **Overhang:** Excess material creating a shelf. - **Open margin:** A visible gap between the restoration and the tooth. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Marginal fit **Effects of open margins:** - Sensitivity - Dissolution of cement - Plaque retention - Caries - Gingival inflammation Open margins can lead to several clinical complications: - Sensitivity - Dissolution of cement - Plaque retention - Secondary caries - Gingival inflammation # TRY-IN PROCEDURE ## SEATING THE CROWN ### Marginal fit - Poor marginal fit can be due to inability to read the finish line by the technician - Overhangs/overextension: can be adjusted - Underextension: may require remake - Gap: require remake #### Corrective Actions for Marginal Errors Poor marginal fit often stems from the technician's inability to clearly identify the finish line. - **Overhangs/Overextensions:** Can typically be adjusted. - **Underextensions:** Usually require a remake. - **Gaps:** Require a remake. # TRY-IN PROCEDURE ## SEATING THE CROWN - **Marginal fit** - Gingivo-occlusal direction - Occluso-gingival direction - Both - New impression  #### Directional Assessment Evaluate marginal fit in the: - Gingivo-occlusal direction - Occluso-gingival direction - Both directions simultaneously If fit is inadequate, a new impression is necessary. # TRY-IN PROCEDURE ## SEATING THE CROWN ### Marginal fit Adjust overextended margins or overhangs from the external surface, not the fitting surface <img src="https://i.imgur.com/2X5vZ5k.png" alt="Diagram showing the seating of a crown with correct and incorrect marginal fit.">  Adjust overextended margins or overhangs from the **external surface** only. Do not adjust the fitting (internal) surface, as this will compromise the seal. Once the crown is seated, it must be assessed for stability, contour, occlusion, and aesthetics to confirm suitability for cementation. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Aims - Check - Stability - Contour - Occlusion - Aesthetics - Confirm the suitability for cementation #### Evaluation Criteria - **Stability:** Ensure no movement under force. - **Contour:** Verify physiological and aesthetic shapes. - **Occlusion:** Check contacts in all movements. - **Aesthetics:** Confirm shade and form match. - **Final Goal:** Confirm suitability for permanent cementation. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Stability - Restoration should not rotate when the force is applied - Instability causes failure in function (mainly in cementation) internal surface misfit caused by distortion in impression or fabrication process <img src="https://i.imgur.com/1234567.png" alt="Diagram showing a crown on a tooth with a green arrow indicating force and a pink dot indicating a point of measurement.">  #### Testing Stability - The restoration should not rotate or rock when force is applied. - Instability often leads to cementation failure. - **Causes:** Internal surface misfit due to distortion in the impression or fabrication process. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Contour - Improper contour may impair gingival health and affects the natural appearance - They must be adjusted before cementation  #### Gingival Health and Aesthetics - Improper contour can impair gingival health and negatively affect natural appearance. - Contours must be adjusted and polished before cementation. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - The crown should be fully seated - Major adjustments should be done prior to cementation - Minor adjustments can be completed after cementation - Inadequate occlusal contacts can be caused by - Poor occlusal recording - Poor articulation #### Occlusal Principles - The crown must be fully seated before checking occlusion. - **Major adjustments:** Perform prior to cementation. - **Minor adjustments:** Can be completed after cementation. - **Causes of inadequate contacts:** - Poor occlusal recording - Poor articulation # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - **Shim stock assessment** - The shim stock will determine if an occlusal contact is present - Assess the occlusion on all teeth with and without the prosthesis - Assess the occlusion on the crown 8-10 μm thick <img src="https://i.imgur.com/1234567.jpg" alt="Close-up of a dental crown being assessed with a shim stock">  #### Use of Shim Stock (8-10 μm) - Shim stock determines if an occlusal contact is present. - **Procedure:** 1. Assess occlusion on all teeth without the prosthesis. 2. Assess occlusion with the prosthesis in place. 3. Specifically assess the contact on the crown itself. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - Articulating paper assessment - Mark heavy contacts or interferences in centric and eccentric - Articulating paper will locate the contact area - Use different colors for different movements     #### Locating Contacts - Use articulating paper to mark heavy contacts or interferences. - Evaluate both centric and eccentric movements. - Utilize different colors of paper to distinguish between different mandibular movements. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - Dark articulating paper (blues) for CR or maximal intercuspation position - Lighter articulating paper (red) for eccentric position <img src="image.png" alt="Assessment of the seated crown with occlusion markings and labels for protrusion, lateroprotrusion, and MIC." />  #### Color Coding Movements - **Dark paper (e.g., Blue):** Used for Centric Relation (CR) or Maximal Intercuspation Position (MIC). - **Lighter paper (e.g., Red):** Used for eccentric positions (protrusion, lateroprotrusion). # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion  *(Page intentionally left blank or contains no unique text content)* # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN   *(Page intentionally left blank or contains no unique text content)* # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - **Premature contact (centric)** - Adjust grooves or cusp inclines - Never the tip of cusp - **Interferences (eccentric)** - Adjust cusp inclines - Tip of cusps if necessary  #### Adjustment Protocols **Premature Contact (Centric):** - Adjust grooves or cusp inclines. - **Constraint:** Never adjust the tip of a functional cusp. **Interferences (Eccentric):** - Adjust cusp inclines. - Adjust the tip of cusps only if absolutely necessary. # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Occlusion - Completed adjustment - Well distributed occlusal contacts - Posterior teeth: the prosthesis and the remaining dentition should have the same occlusal contact and hold shim stock - Anterior teeth: the prosthesis should lightly hold shim stock if other anterior teeth do  # TRY-IN PROCEDURE ## ASSESSMENT OF THE SEATED CROWN ### Finishing and Polishing - **Metal**: rubber polishing wheels and points - **Ceramic**: Rough ceramic will wear the opposing teeth - Composite finishing rubber burs - Rubber cup and diamond polishing paste - Or send to laboratory for reglazing # TRY-IN PROCEDURE ## Systematic approach 1.
