Extraction of an ectopic supernumerary tooth through nasal cavity with piezosurgery under local anesthesia: A case report.

Key Clinical Message: The ectopic supernumerary teeth (ST) commonly occur in the oral cavity. Ectopic ST in the maxilla can be extracted not only through an intraoral approach but also through a nasal approach.

Abstract: The ectopic supernumerary teeth (ST) commonly occur in the oral cavity.

Combined application of artificial bone powders and concentrated growth factor membranes on the autotransplantation of mature third molars: A 5-year retrospective case series.

Aim: This study aimed to observe the efficacy and outcomes of the combined application of artificial bone powder and concentrated growth factor (CGF) membranes for tooth transplantation in cases with wide recipient sockets and small donor teeth.

Material And Methods: A total of 36 teeth from 36 patients with wide recipient sockets and small donor teeth were enrolled. Autogenous tooth transplantation was performed using bone powders and CGF membranes.

Midterm outcomes of autogenous mature third molars transplantation into surgically created sockets: A retrospective cohort study.

Background/aims: The purpose of this study was to observe the outcome of mature third molars transplantation into surgically created sockets with the assistance of computer designed three dimensional (3-D) printed replicas and compare its outcome with the conventional fresh socket autotransplantation.

Material And Methods: This study included total of 96 mature third molars autotransplanted in 96 cases with the guidance of computer designed 3-D printed replicas. Forty-eight teeth autotransplanted into surgically created sockets were enrolled into the surgically created socket group and 48 teeth conventionally autotransplanted into fresh sockets were enrolled into the fresh socket group.

A clinical study of the piezosurgery, high-speed contra-angle handpiece, and the combined application of both for extraction of embedded supernumerary teeth.

Objectives: To compare the effectiveness of three methods: high-speed contra-angle handpiece (HSCAH), piezosurgery, and combined in the extraction of different locations and types of embedded supernumerary teeth.

Methods: Sixty cases with different locations and different types of embedded supernumerary teeth were randomly divided into three groups for extraction by HSCAH, piezosurgery, and the combination of both, and the intraoperative and postoperative conditions of the three groups were compared and analyzed.

Results: In the extraction of embedded supernumerary teeth in the inverted, horizontal, and root tip positions, the piezosurgery group required significantly longer operative time and reduced intraoperative bleeding compared with the HSCAH and the piezosurgery combined with the HSCAH; it could effectively relieve postoperative pain and facial swelling.

Clinical application of concentrate growth factors combined with bone substitute in Alveolar ridge preservation of anterior teeth.

Objective: To investigate the clinical effect of concentrated growth factors (CGF) combined with deproteinized bovine bone mineral (DBBM) on Alveolar ridge preservation during implantology.

Methods: A total of 38 patients were selected and randomly divided into 2 groups, with 19 cases in each group. The extraction sockets were filled with DBBM with or without CGF.

Application of concentrated growth factor to autotransplantation with inflammation in recipient area.

Objective: The purpose of this study was to apply concentrated growth factor (CGF) to the transplanted area with inflammation, to observe the clinical effects of CGF on the inflammation area assisted by 3D printing technology.

Methods: A total of 52 compromised mandibular first or second molar with chronic periapical lesions were transplanted with mature third molars. The patients were divided into CGF group (n = 26) and control group (n = 26) and transplanted into fresh extraction sockets with or without CGF.
