The accidental displacement of roots, endodontic mate­ rials, and dental implants into the maxillary sinus is a relatively common complication in dental clinical prac­ tice [1]. Migration of implants into the maxillary sinuses (during surgery or after a period of function) has been reported [2­9]. Displacement of implants in the sphenoid [10] and ethmoid sinuses [11] has also been described in ...

PURPOSE The aim of this study was to assess the feasibility of biodegradable polyurethane (PU) foam for closure of oroantral communications (OACs). PATIENTS AND METHODS Ten consecutive patients with OACs (existing <24 hours) were treated with PU foam. Standardized evaluations were performed at 2 weeks and 8 weeks after closure of the OAC. RESULTS In 5 patients, the OACs were closed successf...

OBJECTIVES Surgical removal of third molars is a regular surgical procedure, which like all operations, may have complications. The purpose of the study was to analyze the incidence of complications and their relationship with the surgical difficulty in a group of 588 patients treated by the same oral and maxillofacial surgeon. STUDY DESIGN This retrospective cohort study consisted of 1699 th...

OBJECTIVES Head and neck reconstruction is still challenging in terms of esthetic and functional outcomes. This study investigated the feasibility of the angular branch-based scapular tip free flap (STFF). METHODS This was a retrospective study of 17 patients undergoing maxillectomy and mandibulectomy and either primary or secondary reconstruction by STFF. This study included surgical, esthet...

Complications involving cheek teeth extractions are prevalent. More than half of all cheek teeth extraction cases have a potential for complication. Complications may involve surrounding bone, sinus, soft tissue (peridontium, vascular, nerves, etc), and teeth. The extraction process should never be viewed as a simple one-stop procedure. In contrast, an extraction should be a process that involv...

The possible complications of wisdom-tooth removal must be considered, because it is the most common surgical intervention in dental practices. This retrospective study assessed the complications occurring during the removal of 1,562 maxillary wisdom teeth in 1,212 patients. A total of 543 cases of surgical removal and 1,019 cases of non-surgical removal were analyzed. In all cases, a pre-opera...

PURPOSE To assess the survival rate of zygomatic implants (ZIs) and the prevalence of complications based on previously published studies. MATERIALS AND METHODS An electronic search of 3 databases was performed in December 2015 and was supplemented by manual searching. Clinical series of ZIs were included. Interval survival rate and cumulative survival rate (CSR) were calculated. The untransf...
