Background: To compare the effects of first premolar extraction, molar distalization, and non-extraction treatments on the angulation and vertical positions of maxillary second molars (MxM2s) and maxillary third molars (MxM3s). To our knowledge, this is the first study to compare the effects of three different treatment types on MxM3 simultaneously.
Methods: Initial (T0) and final (T1) panoramic radiographs of three different patient groups were analyzed: first premolar extraction group (n = 26 patients, 52 MxM2, 52 MxM3), molar distalization group (n = 20 patients, 40 MxM2, 40 MxM3), and non-extraction group (n = 31 patients, 62 MxM2, 62 MxM3).
Aim: This study aimed to evaluate OccluSense's reliability against conventional articulating films in assessing static occlusion. The study also targets to identify possible limitations and influencing factors when using this device to asses static occlusion.
Materials And Methods: This experimental research utilized twenty epoxy resin typodont models representing various occlusal discrepancies.

To observe the stability of vertical dimension of occlusion (VDO) and mandibular position in full-mouth occlusal reconstruction subjects by means of digital occlusal analysis. Six subjects who had completed full-mouth occlusal reconstruction by intraoral functional generated path technique for more than three years in the Department of Prosthodontics, Peking University School and Hospital of Stomatology were enrolled for follow-up observation, all six patients were male, with an age of (53.6±8.

Purpose: We present a case of transmuscular migration of a solid encircling silicone band through all four rectus muscles.
Observations: A 33-year-old male with high myopia presented with a progressively worsening subclinical peripheral rhegmatogenous retinal detachment in his left eye. An encircling silicone band (#240) was placed anterior to the equator, and 5-0 polyester sutures (Ethicon, Inc.

Background: Lip behaviors can lead to maxillofacial developmental disorders such as anterior open bite, posterior crossbite, increased overjet, and a higher risk of developing a Class II malocclusion. However, lip-sucking, a behavior often underreported and overlooked, may adversely affect the periodontal health of permanent teeth in adolescents under extreme conditions if not promptly identified and managed.
Case Presentation: We report a unique case of an 11-year-old boy with a severe periodontal-endodontic lesion on tooth 32, caused by prolonged, high-frequency, and high-intensity lip sucking.
