Success and failure rates of 9 mm or shorter implants in the replacement of missing maxillary molars when restored with individual crowns: preliminary results 0 to 84 months in function. A retrospective study.

BACKGROUND: The ability to utilize shorter implants in the reconstruction of the posterior maxilla would, theoretically, simplify therapy by lessening the need for augmentation surgery. The purpose of this retrospective study was to assess the success and failure rates of < or = 9 mm or shorter implants in the maxillary posterior regions restored with individual crowns. METHODS: A total of 979 implants were placed in maxillary molar positions and restored with individual crowns. The implants were followed in function for up to 84 months. The results are discussed in terms of clinical applicability and indications for use. RESULTS: The cumulative success rates in function were 94.5% for implants in the maxillary first molar positions and 98.7% for implants in the maxillary second molar positions, yielding an overall cumulative success rate of 95.1%, in function for up to 84 months. CONCLUSION: These findings suggest that non-countersunk implants of 7 to 9 mm in length may be successfully restored with single crowns in the maxillary molar region.

Early and immediately restored and loaded dental implants for single-tooth and partial-arch applications.

PURPOSE: The objective of this consensus committee report was to review the available literature published predominantly in refereed journals to summarize findings, data, and conclusions as they related to reduced healing times and protocols for single-tooth and partial-arch clinical situations. Early loading of dental implants has been defined as restoration of implants in or out of occlusion at least 48 hours after implant placement, but at a shorter time interval than conventional healing. Immediate loading or restoration has been defined as attachment of a restoration in or out of direct occlusal function within 48 hours of surgical placement. MATERIALS AND METHODS: Six articles addressing early loading, with a mixture of single-tooth and partial-arch clinical conditions and including some controlled cohort studies, were reviewed. Immediate loading or restoration of dental implants in single-tooth and partial-arch applications, was extensively reviewed. An attempt was made to isolate and categorize similar case types to discern trends and relevant factors. Variables that were considered included single- or multiple-tooth conditions, immediate or delayed placement in extraction sockets, effect of implant surface and geometry, bone quality, implant stability, surgical technique, occlusal design, effect of cigarette smoking, and stability of results. RESULTS: Combined data from 6 early loading studies on single-tooth and partial-arch applications revealed 1,046 implants with a survival rate of 98.2%. Long-term data for most of the early loading studies were not yet available. Most of the publications on immediate loading or restoration of dental implants were written as case series rather than scientific studies. DISCUSSION AND CONCLUSIONS: In general, most publications indicated that with attention to appropriate factors, implant survival with immediate restoration was comparable to the results with conventional and early loading protocols. It should be recognized that, with few exceptions, these conclusions may be misleading statistical phenomena of the authors, as most publications were written by exceptionally experienced, highly skilled practitioners working under tightly controlled clinical conditions on a relatively small, statistically inconclusive number of implants and patients.

Early loading with the ITI SLA surface as a predictable, routine procedure.

BACKGROUND: Historically replacement of missing teeth with dental implants often required multiple surgical procedures and long delays between initiating and completing treatment. CASE DESCRIPTION: This case describes accelerated implant restoration of teeth #29 and #30 on a 67-year-old male with a history of bruxism and a failed fixed partial denture. The abutments were connected and final restorations were begun 42 days following implant placement surgery. CLINICAL IMPLICATIONS: Ideal results following implant placement can be obtained in less than 10 weeks.

A concept for a biologically derived, parabolic implant design.

It has become widely accepted that modern titanium dental implants are successful and predictable. However, there is bone loss in relation to any interface (microgap) that occurs between the implant parts when the microgap is in proximity or apical to the osseous crest. The principle of biologic width may be responsible for such bone remodeling in an apical manner. A new, biologically derived implant design that conceptually may minimize bone remodeling and promote better bone and overlying gingival contours and stability is suggested. The parabolic occlusal platform of this design is in harmony with the biologic width of the soft tissue around the circumference of the implant when the proximal bone is occlusal to the facial and lingual bone. Preservation of proximal bone for an isolated implant, and between implants, will help support and maintain physiologic and cosmetic gingival contours and papillae. This is of particular importance in esthetic areas, where interproximal bone loss between implants or between an implant and an adjacent tooth may cause a reduction in gingival papilla height.

Multicenter retrospective analysis of the solid-screw ITI implant for posterior single-tooth replacements.

PURPOSE: This report involves the retrospective analysis of ITI implants placed and/or restored by a group of 7 clinicians located throughout the United States (5 periodontists and 2 prosthodontists). MATERIALS AND METHODS: Six hundred seventy-five posterior single-tooth implants were restored in 471 patients (average time of loading 21.30 months, with a range of 1 to 78 months). Three hundred seventy implants and 71 implants were placed in mandibular and maxillary molar sites, respectively, and 108 and 126 were placed in mandibular and maxillary premolar sites, respectively. RESULTS: A cumulative survival rate of 99.1% was obtained for all sites (6 failures). The survival rates for individual sites were as follows: 98.4% mandibular molars, 100% maxillary molars, 100% mandibular premolars, and 100% maxillary premolars. "At-risk" implants (1 to 2 mm of radiographic bone loss) were noted at 5 sites. DISCUSSION: Minimal restorative problems were found with either screw-retained (n = 71) or cemented restorations on solid abutments (n = 600); 80.3% of screw-retained and 98.2% of cemented restorations were free of complications, respectively. Patient satisfaction scores were high (97.4%) as determined by the Patient Satisfaction Questionnaire. CONCLUSION: The data suggest that solid-screw (4.1 or 4.8 mm wide) ITI implants can be a satisfactory choice for posterior single-tooth restorations.
