Objective: The purpose of this perspective research was to study the long-term stability of skeletal, dentoalveolar and soft tissue after orthognathic surgery in subjects presenting with Class II and Class III malocclusions.
Methods: The available digitized cephalometric radiographs, including pretreatment (t0), presurgery (t1), a minimum of 12 months postsurgery (t2) and at least 3 years after the orthosurgery treatment (t3) were taken between 1998 and 2010. In Group 1 mandibular advancement and in Group 2 mandibular advancement and maxillary impaction surgery were performed for correction of Class II. In Group 3 maxillary advancement and in Group 4 surgical maxillary advancement with mandibular setback, for correction of Class III.
Results: In all the phases mandibular length was shorter in Group 1, and the inferior third of the face was longer in Group 2. Before the surgery there was greater maxillary deficiency in Group 3 than Group 4 and mandibular length was longer in Group 4.
Conclusion: In Groups 1 and 2, at retention phase, relapse occurred due to the increase in mandibular plane, whereas the surgeries performed in Groups 3 and 4 remained stable.

The effect of occlusal balance and prosthesis on occlusal function of patients after dental implant restoration.
Heliyon
January 2025
Stomatology Medical Center, Aviation General Hospital, Beijing, China.
Objective: This observational study investigated the relationship between occlusal balance and the tightness of restorative-contralateral occlusal contact in patients undergoing dental implant restorations.
Methods: A total of 100 patients who received dental implant restorations at our hospital between July 2022 and July 2023 were included. Patients were divided into two groups based on occlusal closeness: an observation group (using 12 μm occlusal paper for occlusion) and a control group (using 20 μm occlusal paper for occlusion).

Background: Aim of the present paper is to report the preliminary results of CAD-CAM (Computer-Aided Design - Computer-Aided Manufacturing) technology application to distal femur nonunion treatment with free fibula flap, custom made medial plating and maintenance of a stable lateral locking plate.
Methods: Two cases of distal femur nonunion that occurred after lateral locking plating were treated and prospectively followed-up. Surgical planning followed the same preoperative protocol adopted for mandibular CAD-CAM reconstruction.
Topographic Evaluation of Inflammatory Periapical Lesions in the First Molar's Region Using CBCT.

Investigating the pattern of extension in the periapical (PA) inflammatory lesions is important in the treatment plan and prognosis of treatment. This study evaluated the topography of PA inflammatory lesions in the first molars using cone-beam computed tomography (CBCT). In this descriptive study, 197 CBCT images about patients in the age group of 14-77 years were analyzed.

Although the deep circumflex iliac artery (DCIA) flap is a mainstay in mandibular reconstruction, its multi-segmental utilization is infrequently reported, primarily due to concerns regarding the variable cutaneous component and potentially inadequate vascular supply to multi-block segments. This retrospective study analyzed the outcomes of 86 patients undergoing mandibular reconstruction with multi-segmental DCIA flaps, compared to 167 patients who received conventional single-segmental flaps. The survival rate for multi-segmental flaps was comparable to that of single-segmental flaps (100% vs.
