Interim complete immediate dentures for a patient wearing removable partial dentures.

This article describes a technique used for fabricating temporary (interim) complete dentures for a patient who had been wearing removable partial dentures and whose remaining teeth were to be extracted. Rather than attempt to incorporate the existing removable partial dentures into the interim complete dentures, the dentist used the existing dentures to fabricate acrylic resin teeth for the interim prosthesis.

Treatment of completely edentulous patients with fixed implant-supported restorations: three consecutive cases of simultaneous immediate loading in both maxilla and mandible.

This article aims to: (1) describe the treatment of three consecutive completely edentulous patients with fixed implant-supported restorations, including simultaneous same-day immediate loading with fixed provisional restorations in both jaws; and (2) illustrate a step-by-step definitive restoration approach. All patients followed the same diagnostic protocol. One surgical intervention was performed for simultaneous implant placement in both maxilla and mandible. Following implant placement, all patients received a simultaneous, same-day, complete-arch, screw-retained provisional restoration in both jaws according to the "pickup" technique. After healing, final impressions were taken, and occlusion recorder devices were prepared on working casts. For the first occlusal record, the "half-provisionals" method was used. Definitive solid abutments were used for both laboratory and clinical procedures. After casting and finishing, the frameworks were tried in, and a new occlusal record was made. The definitive segmented restorations consisted of four fixed partial dentures in the maxilla and three in the mandible and were cemented with provisional cement. All patients received a nightguard. The pickup technique facilitated simultaneous immediate loading in both maxilla and mandible. A complete, fixed, segmented rehabilitation supported by six to eight anteroposterior implants is a reproducible treatment for completely edentulous patients when optimal anatomic conditions are present.

A short-term clinical evaluation of immediately restored maxillary TiOblast single-tooth implants.

PURPOSE: The purpose of this study was to evaluate the short-term clinical outcome of single-tooth implants placed in the maxilla and immediately restored using cementless friction-fit temporary crowns. MATERIALS AND METHODS: Twenty-five patients consecutively referred to a private specialist practice for the replacement of failing or missing maxillary teeth were treated by means of immediate temporization of their single-tooth implants. Where teeth were still present, implants were placed immediately following extraction. Provisional crowns were fabricated on a special friction-fit coping by means of autopolymerizing acrylic resin. Definitive crowns were placed a mean of 4.5 months after surgery. Implant survival was recorded along with the level of the marginal bone relative to a fixed reference point 1 year after placement. Any adverse soft tissue changes were also noted. RESULTS: A total of 28 Astra Tech ST dental implants were placed. The overall survival rate at the end of the study was 96.4% for implants which were in function for periods ranging from 15.7 to 27 months. One patient, a smoker, lost 1 implant within 1 month of surgery. Mean marginal bone loss was 0.40 mm (range 0 to 1.53 mm) 1 year after placement of the implants. Many implants (37.5%) had no observed bone loss. No implants or crowns have been lost during the functional loading period. One implant was associated with an unfavorable recession of soft tissues; however, most maintained an esthetic gingival architecture. Eleven of 28 provisional restorations needed treatment; 6 required replacement during the temporization period, and 5 required cementation because of looseness. The ease of removal of the crowns allowed regular access for irrigation with chlorhexidine and thus maintenance of soft tissue health. DISCUSSION: The need to provide provisional restorations for single-tooth gaps often presents challenges. An immediate temporary partial denture or adhesive prosthesis may be unacceptable or impractical. The current study describes a simple method for the immediate temporization of single-tooth implants. The results did not indicate any negative influence on osseointegration or short-term survival once the implants were functionally loaded. CONCLUSION: Immediate temporization of maxillary single-tooth implants can be both safe and predictable, and it appears that the procedure can yield favorable soft tissue esthetics.
