Objective: To study the technical refinements of intraoral reduction malarplasty to prevent postoperative drooping of the cheek.
Methods: Twenty-four patients with prominent zygomatic complex underwent reduction malarplasty from January 2005 to January 2006. In all these cases, the osteotomized malar complex was repositioned superioposteriorly, and the perioral muscles and periosteum were redraped accordingly and fixed on deep temporal fascia.
Results: Symmetry between the left and right complexer were achieved, with a decreased midfacial width of 10.22-/+1.97 mm. During postoperative follow-up of 4 to 6 months, all the patients had satisfactory operative results, and reported no postoperative drooping of cheek.
Conclusion: This method of superioposterior reduction of the perioral muscles and periosteum is simple and effective, but the long-term result needs to be observed.

Obstructive sleep apnea (OSA) causes intermittent hypoxia, increased production of reactive oxygen species, and inflammation, which may elevate morbidity and mortality from cardiovascular disease. The objective of the present study was to investigate the effect of the intraoral appliance (IOA) as a treatment for OSA when it comes to the modulation of inflammatory markers and oxidative damage in elderly individuals. This "before and after" clinical trial included 9 patients diagnosed with OSA recruited from a multicenter randomized clinical trial study that evaluated the treatment with IOA for 60 days.

The study aimed to assess the impact of combining potassium iodide (KI) with methylene blue (MB) in antimicrobial photodynamic therapy (aPDT) within an oral biofilm formed in situ. A single-phase, 14 days in situ study involved 21 volunteers, who wore a palatal appliance with 8 bovine dentin slabs. These slabs were exposed to a 20% sucrose solution 8 times a day, simulating a high cariogenic challenge.

Aim: To compare the accuracy and treatment time of a robotic system (RS) and a dynamic navigation system (DNS) in osteotomy and root-end resection in an in vitro study.
Methodology: In this study, four identical mandibular models were created using three-dimensional (3D) printing, each model including 18 teeth. In the surgical procedures, teeth #35, #33, #32, #42, #43 and #45, along with the mesiobuccal roots of teeth #36 and #46, were specifically selected for operation on each model.

Background: Understanding the disease-specific risks and patient-related barriers of children with bleeding disorders is necessary for primary oral health promotion. Our goal was to assess the oral health status and the impact of oral health promotion among patients with bleeding disorders.
Research Design And Methods: At baseline, 70 patients with inherited and acquired bleeding disorders had a complete intraoral examination, completed the oral health-related quality of life (OHRQoL) questionnaires, and an oral health education was given.

Background/objectives: This study aimed to compare the cost and time implications for implant-supported prosthesis comparing three digital impression techniques: digitization with an intraoral scanner, digitization of the conventional impression (without dental casts) and digitization of the stone models.
Methods: To assess the time and cost of digital impression techniques on implants, time records on intraoral scans were consulted and three models were created with one, two and six implants to assess extraoral procedures time. Costs were evaluated based on material consumption, time expenditure and operator-related expenses.
