Periapical Lesion on an Implant after Socket Shield Technique: A Case Report.
Periapical Lesion on an Implant after Socket Shield Technique: A Case Report. J Int Acad Periodontol. 2019 Jan 31;21(1):29-35 Authors: Stuani VT, Manfredi GGDP, Sant'Ana ACP, de Rezende MLR Abstract A 47-year-old Caucasian male presented with a radiolucent area around the apical region of an implant placed using the socket shield technique. A second surgical procedure was performed to curette the lesion and fill the defect with a xenogeneic bone graft. Twenty months after implant placement and 10 months after the second surgery, there was no sign of recurrence of the lesion and radiographic evaluation was consistent with new bone formation in the region. Thus, although numerous studies have demonstrated the effectiveness of the socket shield technique, this case report illustrates the need for further randomized clinical studies for a better understanding of the clinical complications and indications for the technique.

ConclusionBimeniscal replacement by an allograft and/or substitute provides good short-term functional and anatomical outcomes. Nevertheless, this procedure is warranted only in highly selected patients.Level of evidenceIV, retrospective study.
Structural glenoid bone grafting in reverse total shoulder arthroplasty (RSA) has previously been reported to have good functional outcomes and low complication rates. We have observed different complication rates and hypothesized that baseplate fixation and severity of deformity may be predictors of early failure.
Conclusion: Our study demonstrates that the new comprehensive protocol is extremely effective for achieving sound union in Congenital Pseudarthrosis of Tibia.
Acellular human dermal allograft commonly is used in the surgical treatment of complex rotator cuff tears, but little information is known about the biological fate of these grafts in human subjects. In this case report, the authors describe a patient who presented with a radiographically healed acellular human dermal allograft superior capsular reconstruction but had humeral head avascular necrosis. The healed superior capsular reconstruction, including graft −bone interfaces, was explanted after 7 months and sent for histologic analysis.
A structural graft is often used to maintain correction and achieve union after anterior calcaneal lengthening osteotomy for treatment of flexible flatfoot. Autograft, the current gold standard, is limited in availability and configuration and is associated with donor site morbidity in as much as 48%, whereas the alternative allograft carries risks of disease transmission and collapse. Polyaryletherketone cage, with a healing rate similar to that of autograft, high stability, and no donor-site morbidity, has been used in spine surgery. However, its use has not been documented in foot and ankle surgery. We reviewed 15 patie...
ConclusionsUltrasound imaging can be a useful tool for the monitoring of apical surgery outcomes without ionizing radiation. Further research is essential with inclusion of more patients.
Conclusions: Cancellous particulate allograft bone demonstrated excellent bone regeneration behavior both in terms of quantity and quality, and stable results over a 6-year period. Clinical Relevance: Cancellous allograft bone can be successfully used to regenerate atrophic sites.
ConclusionsAnatomic ACL reconstruction could restore not only the normal anterior knee laxity, but also the normal tibiofemoral relationship even under an anterior tibial load.
CONCLUSION: Within the limits of this study, this case series study suggests that chitosan gel, along with bovine porous bone mineral, has a promising role to play in periodontal regeneration. PMID: 31522157 [PubMed - in process]
ConclusionOur study showed that cigarette smoking did not have negative effect on union time in the metaphyseal region after correction osteotomy. The time of bone-union in heavy-smokers was 2.5 weeks more than that of non-smokers.
