Multiple dental impactions not associated with craniofacial syndromes are a rare condition and present the dentist with a therapeutic challenge when it comes to performing surgical/restorative treatments in adult patients. This case report describes a geriatric patient with multiple impacted teeth restored by means of two different protocols. In the second quadrant, an impacted tooth was extracted followed by regeneration and placement of an implant. In the third quadrant, implants were placed though impacted teeth for restoration with a fixed partial prosthesis. Placing dental implants through impacted teeth may offer a possible therapeutic option for implant-supported restorations in middle-aged or elderly patients, for whom surgery and orthodontic traction are not possible, and/or patients who refuse to undergo more invasive extraction surgery.

Objective: The aim of this study is to determine the contact relationship and position of impacted mandibular third molar teeth (IMM) with the mandibular canal (MC) in panoramic radiography (PR) images using deep learning (DL) models trained with the help of cone beam computed tomography (CBCT) and DL to compare the performances of the architectures.
Methods: In this study, a total of 546 IMMs from 290 patients with CBCT and PR images were included. The performances of SqueezeNet, GoogLeNet, and Inception-v3 architectures in solving four problems on two different regions of interest (RoI) were evaluated.

: Impacted third molar extraction with a scalpel and rotary instruments is one of the most traumatic surgeries in dentistry. Therefore, it is necessary to discover less traumatic methods and instruments to reduce the risk of postoperative complications. : This study is reported in accordance with the CONSORT guidelines.

Purpose: To investigate the changes of root development before and after orthodontic traction of maxillary inverted impacted central incisors using CBCT and Mimics software.
Methods: Ten patients, who had a maxillary inverted impacted central incisor, were treated using a modified movable retractor combined with surgical eruption. Cone-beam computed tomography(CBCT) was taken before and after treatment.

Purpose: To analyze the safety of closed traction appliance in the treatment of impacted anterior teeth and its effect on pulp blood flow and masticatory function.
Methods: A total of 80 patients with impacted anterior teeth who received treatment from January 2017 to December 2022 were selected, and randomly divided into experimental group and control group with 40 cases in each group. The two groups of patients were treated with occlusion adjustment and orthodontic traction.
