Digital robot-assisted minimally invasive impacted tooth extraction: A case report.

Objective: This study investigated the clinical effects and applicability of minimally invasive impacted teeth extraction using digital robots.

Methods: A marker was bonded to the non-surgical area before surgery. A Cone-Beam Computed Tomography (CBCT) scan was obtained and uploaded to the robot software to determine the drilling position of the ring drill.

Personal Guide Assisted Orthognathic Surgery: Application of a T-shaped Tooth Bone Combined Supporting Osteotomy Guide Plate and Positioning Guide Plate.

The precise movement of the maxilla is particularly important for orthognathic surgery, especially for patients with maxillary segmentation. In this preliminary study, the authors present a new tooth bone combined with a supporting osteotomy guide and positioning guide to guide the osteotomy and reduction of the maxilla. Through our preoperative simulation and postoperative image fusion, the authors found that the overlapping area is more than 90%.

[Use of "gelatamp" colloidal silver gelatin sponge to prevent dry socket after extracting mandibular impacted teeth].

Purpose: To study the clinical effect of "gelatamp" colloidal silver gelatin sponge on preventing dry socket after extracting the mandibular impacted teeth.

Methods: 1350 teeth extracted from 976 patients who needed to extract the mandibular impacted teeth were divided into group A, group B and group C randomly. "Gelatamp" colloidal silver gelatin sponge was implanted into alveolar socket after teeth extraction in group A, with absorbable gelatin sponge was implanted into alveolar socket in group B and nothing was implanted into alveolar socket in group C.

[Double root canal of all mandibular incisors: report of one case and review of the literature].

Mandibular incisors are the smallest human permanent teeth with complex root canals. Double root canal, lateral branch of root canal, apical ramification or apical furcation usually happen, which make the clinical therapy more difficult. In this paper, a case of mandibular incisors with double root canals was reported, the root canal type and its incidence were discussed.
