Pressure to deliver implant-born prosthetics in most partially edentulous situations is growing. The implant team is faced with high patient expectations for optimal function and aesthetics while being challenged to restore more complex areas of the jaw. Osseous ridge deficiencies are more often the norm than the exception following tooth loss. Squeezing short or narrow implants into deficient ridges is a poor technique that often fails to properly replace ridge anatomy or provide stable restorations. Bone grafting should assume an essential role to the implant team if their objective is to create biologically sound replicas of missing natural teeth.
A patient presenting with bilateral intermittent mental paraesthesia on wearing a lower denture on a very atrophic ridge was treated with an implant-retained overdenture which resolved her symptoms.
BACKGROUND AND OBJECTIVE: Class III periodontal furcations still represent a challenge for the periodontist. Aim of this study was to test the effect of CO2 laser on the treatment of class III furcation defects. STUDY DESIGN/MATERIALS AND METHOD: Class III furcation defects 3 mm deep were surgically induced on mandibular premolars on six male Beagle dogs, for a total of 36 defects. After 6-8 weeks of plaque accumulation, the mean depth was 6.8 mm. Quadrants were randomly assigned to a) CO2 laser therapy (laser), b) Guided Tissue Regeneration (GTR) procedure using Gore-Tex Membranes, (Gore Tex, Flagstaff, Arizona, USA) and c) Scaling and Root planing (Sc/Rp). CO2 laser beam (El.En, Florence, Italy) was applied to the root surfaces in defocused pulsed mode at 2W, 1 Hz and a duty cycle of 6%, and on periodontal soft tissues at 13W, 40 Hz, and a duty cycle of 40%. Control quadrants received either GTR procedure or Sc/Rp. Mechanical oral hygiene was provided. At 6 months the animals were sacrificed. RESULTS: The laser group showed new attachment formation averaging 1.9 mm (sd +/- 0.5), whereas GTR and Sc/Rp showed 0.2 mm (sd +/- 0.4) and 0.2 mm (sd +/- 0.5) respectively, being the differences statistically significant between the laser group and both GTR and Sc/Rp groups (p < 0.005). CONCLUSION: CO2 laser treatment of class III furcation induced formation of new periodontal ligament, cementum and bone.
