Immediate loading of 190 endosseous dental implants: a prospective observational study of 40 patient treatments with up to 2-year data.

PURPOSE: The present study was undertaken to determine the feasibility of using primary stability as a predictor of implant success in patients whose implants were immediately loaded. MATERIALS AND METHODS: The study included 40 patients, in whom a total of 190 implants were placed, 102 in maxillary sites and 88 in mandibular sites. All were loaded within 72 hours of placement. Sixteen patients were completely edentulous in the mandible and/or the maxilla. The remaining 24, who were partially edentulous, received fixed partial dentures or single-implant restorations. All of the definitive implant restorations were screw retained. The criterion for loading was clinical judgment of primary stability, verified by a "screw test." Impressions were made after implant placement to facilitate the fabrication of a laboratory-made heat-processed provisional restoration from acrylic resin. Following a 4-month period for osseointegration and soft tissue healing, definitive fixed prostheses were fabricated. RESULTS: There were no surgical complications. After 1 to 2 years, all 190 implants had survived and were considered 100% successful, as determined by independent testing of mobility and radiographic evidence of osseointegration. In 4 patients, fracture of the provisional restoration occurred during the healing period. DISCUSSION: Clinical research has shown that immediate loading is a viable treatment modality. The favorable success rate reported in this study for rough-surfaced implants suggests that adherence to a protocol, an important parameter of which is primary stability above 32 Ncm, can lead to osseointegration. CONCLUSION: The results of this limited investigation suggest that patients who are partially or completely edentulous may be immediately restored with implants and fixed provisional restorations, provided that the dental implants are adequately stable immediately after their surgical placement. This alternative therapeutic approach did not appear to affect the up-to-2-year survival of the implants in this patient population.

Root planing with interdental papilla reflection and fiber optic illumination.

The complete removal of accretions during closed scaling and root planing in moderate-deep pockets is difficult, presumably due to inadequate mechanical and visual access. The purpose of this study was to evaluate the effect of minimal papilla reflection and illumination with a prototype fiber optic unit on root planing efficiency. Nonmolar teeth with moderate-deep interproximal pockets (greater than 3 mm) in four patients scheduled to receive immediate complete dentures were randomly divided into groups for treatment: Group I--interproximal root planing augmented by papilla reflection and fiber optic illumination (n = 26 surfaces); Group II--interproximal root planing with papilla reflection only (n = 24); Group III--untreated controls (n = 23). Immediately after treatment, the experimental teeth were extracted, stained with toluidine blue and interproximal areas were evaluated for remaining accretions with a microscope-digitizing pad-computer system. Significantly less (P less than 0.01) root surface was covered by deposits in Group I than Group II (0.57 +/- 0.29% vs. 2.42 +/- 0.63%), and both treatment groups had fewer (P less than 0.0005) accretions than untreated controls (57.72 +/- 3.40%). These results suggest that root planing with papilla reflection produces an interproximal surface with few remaining deposits, and fiber optic illumination and transillumination further enhance this effect.

Specific clinical problem areas.

In this final article of the series, the clinical and technical aspects of a range of similar forms of immediate prosthesis are discussed. Similarly, copy denture and reline/rebase procedures are detailed.

The conversion partial denture: a clinical report.

The treatment alternative described maximizes the benefit of remaining teeth while allowing simplified alteration of the prosthesis if abutments are lost during the life span of the removable partial denture (RPD). A conversion partial is an RPD whose tooth-frame assembly components are individually fabricated and then joined with an acrylic resin major connector. The conversion RPD optimizes retention and stabilization of a terminal dentition and can be easily converted to an immediate complete denture.
