1 Module 2 2 October 2008 Case Presentation Adrian Wong Case Presentation Adrian Wong

2 61 year old Male

3 Cheek biting +++ Food packing +++ Chief Complaint

4 high blood pressure (controlled) gastro- eosophageal reflux Medical History

5 RCTS +++ Restorations +++ Failing Crown and Bridge Dental History

6 Extra-Oral At rest

7 Extra- Oral No tooth display at rest Reverse smile Low lip line Tenderness in Lateral Pterygoids No joint sounds phonetics - “F” not clear and “S” not crisp brachio facial type enlarge massetters and tempoarlis (no tenderness) Class 1 skeletal

8 Reverse Smile Line

9 Low Smile line Poor incisor edge position Central incisors -1:1 square Good midline and no cant (co-incident with facial mid-line) Reasonable Zenith Points Good Buccal Corridor Over eruption Q1 Reverse Smile Diastema Aesthetic assessment

10 INTRA-ORAL

11 Occlusal View LOWER

12 OCCLUSAL VIEW UPPER

13 Caries Attrition severe erosion slight periodontal disease existing crown and bridge failing restorations missing teeth short crown height esp lower posteriors (reflux pattern?) alveolar ridges well developed over-eruption Q1 RCTs +++ Porcelain #+++ Group function - no anterior guidance Slide form CRCP to MIP 0.5mm anteriorly, 0.25mm to RHS, 0.25mm vertical Intra-Oral

14 OPG

15 Risk Factor assessment Heavy bite Parafunction Past # porcelain ++++ RCT reinfection/Mechanical failure High rate of recurrent caries Acidic mouth (Reflux)

16 Treatment plan Preventive treatment - medical assessment and treatment of reflux, use of recaldent chewing gum/tooth mousse, fluoride mouth rinse. Periodontal treatment and maintenance. Endodontic assessment - 25, 26, 37, 36, 35, 47, 48 extraction of 48

17 Full mouth Rehabilitation Rehabilitate to CR/CR with long centric Increase OVD and length of anterior to predetermined position- single point contact cusp-fossa contact posteriorly and immediate disclusion during all excursions.(anterior guidance) Long term laboratory constructed provisionals Composite buildups on lower incisors Gradual conversion of provisionals to final restorations 24, 25, 37, 36, 35, 46 - consider implant replacement

18 Uncertainties Increase in OVD sufficient to eliminate cheek biting? Gold restorations should be material of choice? Composite buildups on lower anterior sufficient? Longevity of Provisionals Incisors too long? Too much anterior tooth display given age and long upper lip
