Does the implant-abutment interface interfere on marginal bone loss? A systematic review and meta-analysis.

The objective of this systematic review was to compare the conical internal connection (IC) with the external hexagonal connection (EH) on the occurrence of marginal bone loss (ΔMBL). Different databases were used to carry out the selection of the elected studies. The studies were judged according to the risk of bias as "high", "low" and "unclear" risk.

Immunolocalization of IP3R and V-ATPase in Ameloblastomas.

The goal of this study was to investigate the immunolocalization of inositol 1,4,5-trisphosphate receptor (IP3R) and vacuolar ATPase (V-ATPase) in ameloblastomas with special attention to the invasive front. Thirty-seven cases of previously diagnosed formalin-fixed paraffin-embedded (FFPE) human ameloblastoma samples were selected for this study. The samples were grouped according to the predominant histologic pattern and comprised twelve plexiform, eighteen follicular, and seven unicystic ameloblastomas.

Temporal Flap as an Option for Buconasal Fistula Closure.

Maxillary defects with buconasal/businusal communications are situations difficult to manage and solve. Several treatment options are available on the literature, each one with its indication. Temporal muscle flap is one of these options, being a technique that requires more experience of the surgeon to be properly performed and that is mainly indicated for difficult cases, large defects and those nonresponsive to simpler techniques.

Pedicle Tongue Flap for Palatal Fistula Closure.

Background: Palatal fistulae are common sequels that appear in patients after surgical procedures in the palate. Considering the difficulty to achieve an effective treatment, there are many techniques to surgically manage fistulae, that is, the pedicle tongue flap.

Objective: Being so, the main goal of this paper is to report cases of patients with palatal fistulae, from different etiologies, treated with anterior pedicle tongue flap.
