Listed below are important areas to inspect when evaluating dental implants:
1. Materials / Type of Implant and Restoration
3. Plaque / Calculus
4. Probing / Bone levels
5. Bleeding / Suppuration
6. Recession / Attachment
7. Color of Gingiva and Restoration
8. Occlusion / Wear
9. Contact points / Contours
11. Radiographic evaluation
Listed below are important risk factors for peri-implant inflammation:
1. Previous periodontal or peri-implant disease
2. Plaque control / inability to clean
3. Residual cement
6. Uncontrolled diabetes
7. Occlusal overload
New teeth in one day: Immediate Implant Placement and Provisionalization Surgery in the Aesthetic Zone
This surgery involves extraction of one or more teeth, immediate implant placement, and attachment of temporary crown(s) and bridge(s) in just one surgery!
This treatment is preferred by patients for the following reasons:
1) Immediate Aesthetic results.
2) A fixed result.
3) Optimum patient comfort during the healing period.
4) Minimum amount of pain.
5) Minimum number of appointments.
6) Minimum amount of healing time required until final restoration.
7) Prevents collapse of hard and soft tissues.
8) Prevents recession due to due to minimum number of surgeries.
9) In some cases, existing crown or tooth can be attached for optimum aesthetics.
10) In most cases, does not require waiting for lab work. The surgery can be started immediately.
For predictable, excellent results, the specialist must be an expert in performing the following surgical procedures:
1) Atraumatic extractions.
2) Extraction of infected teeth or damaged teeth.
3) Socket degranulation and repair.
4) Immediate implant positioning.
5) Implant stabilization in minimal quality and volume of bone.
6) Hard tissue grafting including buccal plate repair when needed.
7) Soft tissue grafting.
8) Immediate abutment and crown provisionalization.
Technologies and diagnostics that aid the specialist include:
1) Digital radiography and 3D imaging.
2) Implant radiographic stents.
3) Implant surgical guides.
4) Study models and wax-ups.
5) Color-matched acrylic temporary shells.

These are challenging cases with exciting results for patients; additionally, these are great cases for the general dentist and periodontist to work on together. Please feel free to comment about your experiences with this type patient care.
Recent studies have shown that screw-retained implant restorations are more biocompatible than cement-retained restorations. It is therefore recommended that cement-retained restorations be limited to the following situations:
1) When a screw access hole would result in unsupported material (greater resistance to porcelain fracture).
2) When resistance to offset loading is desired (allows forces to be better distributed along the axial inclination of the implant).
3) When a screw access hole would be visible (enhance esthetics).
4) When an intact occlusal surface is desired (occlusal table can be adjusted).
5) To correct implant malposition or angulation.
6) To reduce treatment costs.
7) To simplify the fabrication procedure.
8) When a passive fit is desired (40µm of cement space can compensate for laboratory distortions).
9) When a patient has limited opening.
