ABSTRACT
OBJECTIVE: To evaluate, in a case series, survival rate and complications of Brånemark Integration BioHelix(™) dental implants, placed according to conventional procedures in patients treated consecutively in a Swedish specialist private practice after 5 years. MATERIALS AND METHODS: Eighty-three consecutively-treated patients received 89 final fixed prostheses supported by 310 implants placed according to 'conventional' procedure, i.e. no implants shorter than 10 mm, no immediate post-extraction implants and no bone-grafting procedures. In 70 patients, implants were left to heal submerged, whereas 13 patients were treated according to the one-stage protocol. All implants were incorporated in a prosthetic restoration. Probing was only performed when clinical signs of inflammation were present and this was then evaluated further with intra-oral radiographic examination. Outcome measures were implant survival and prosthetic complications. RESULTS: Five years after implant placement, two fixtures were removed because of loosening. One fixture was lost after 12 months in the lower jaw in one patient and one fixture was lost in the upper jaw in another patient after 3 years, both inserted using the two-stage technique. No other prosthetic complications occurred, giving a 99.3% cumulative survival rate. CONCLUSIONS: Brånemark Integration BioHelix(™) dental implants placed according to one- or two-stage procedures in patients in a private practice produced excellent 5-year results. Randomized clinical trials with suitable controls are suggested to confirm these results.

PURPOSE: To evaluate, in a retrospective case series, survival rates and complications of Brånemark dental implants placed according to 'conventional' procedures in patients consecutively treated in a Swedish specialist private practice. MATERIALS AND METHODS: Eighty-three consecutively treated patients received 89 final fixed prostheses (31 mandibular and 58 maxillary) supported by 310 (101 mandibular and 209 maxillary) implants placed according to 'conventional' procedures, that is, no implants shorter than 10mm, no immediate post-extractive implants and no bone grafting procedures. In 70 patients, implants were left to heal submerged, whereas 13 patients were treated according to a one-stage procedure. All restorations (40 screw-retained cross-arch bridges, 32 screw-retained partial bridges and 17 cemented single crowns) were delivered about 2 (mandible) to 3 or 4 (maxilla) months after implant placement. Outcome measures were prosthesis success, implant survival and complications. RESULTS: One year after implant placement, no patients had dropped-out. No prostheses or implants had failed and no biological or biomechanical complications had occurred. CONCLUSIONS: Brånemark BioHelix dental implants placed according to 'conventional' procedures in 'selected' patients provided excellent short-term results. Randomised clinical trials with suitable controls are needed to confirm these preliminary results.

Aiming at optimizing serotonin levels in endogenous pain-modulating systems, L-tryptophan supplementation pre- and postoperatively (2 g/day for 7 days) did not affect pain development or analgesic consumption after third molar surgery. Biological effects related to an increase in mood were observed, however, indicating transport of L-tryptophan to the central nervous system. The findings are discussed in relation to earlier reports on favorable effects of L-tryptophan on experimental pain in healthy subjects and in chronic pain patients.
