Comparison of Tunnel and Crestal Incision Techniques in Reconstruction of Localized Alveolar Defects.

Purpose: The aim of this study was to compare the complication rates of recipient sites prepared using two incision techniques: crestal and tunnel.

Materials And Methods: In this prospective study, patients underwent augmentation procedures (68 patients; 75 sites) by the same surgeon that were performed consecutively using the crestal incision technique (27 horizontal, 10 vertical; crestal group) or the tunnel incision technique (27 horizontal, 11 vertical; tunnel group). Autogenous bone block grafts were harvested with a piezoelectric surgical device, and the grafts were fixed at the recipient sites by two titanium screws in both groups.

Incidence of root canal treatment of second molars following adjacent impacted third molar extraction.

Background/purpose: The aim of this study was to evaluate the incidence of requirement for root canal treatment of adjacent second molars following the surgical extraction of an impacted third molar.

Materials And Methods: The dental records of 6323 consecutive patients who had impacted third molars removed surgically were evaluated and the incidence of postoperative root canal treatment requirement of adjacent second molars was determined. Patients who required root canal treatment of neighboring second molars were accepted as the study group, while the remaining patients were accepted as a control group.

Comparative evaluation of simultaneous maxillary sinus floor elevation and implant placement with residual bone heights greater or less than 5 mm.

Purpose: Implants can be inserted simultaneously during sinus floor elevation (SFE), or 6 months later, for posterior maxillary rehabilitation. The residual bone height (RBH) is a major factor that affects the type of surgical procedure that will be performed. The aim of this study was to compare the survival rates of implants inserted during one-stage SFE with two different RBHs (< 5 mm and ≥ 5 mm).

Is the incidence of temporomandibular disorder increased in polycystic ovary syndrome?

The prevalence of temporomandibular disorders is higher among women than men (ratio 3:1 -9:1). Polycystic ovary syndrome(PCOS) is the most common endocrine disorder in women, which is characterised by chronic low-grade inflammation and excess of androgenic hormones that lead to metabolic aberrations and ovarian dysfunction. Increased activities of various matrix metalloproteinases (particularly MMP-2 and 9) in the serum of these patients has been reported, and it has been hypothesised that high activities of MMP may contribute to loss of matrix and chronic inflammation of the fibrocartilage in temporomandibular disorders.

Change in inferior sclera exposure following Le Fort I osteotomy in patients with midfacial retrognathia.

Purpose: For facial esthetic reasons, no sclera should be exposed above or below the irises when the head of a patient who has a normal skeletal pattern is in a neutral position and the eyelids are in a relaxed position. This study evaluated the decrease in sclera exposure after maxillary advancement or impaction in patients with midfacial hypoplasia.

Patients And Methods: Forty-seven consecutive patients (24 male, 23 female) who underwent Le Fort I osteotomy were included.

Management of bisphosphonate-related osteonecrosis of the jaw with a platelet-rich fibrin membrane: technical report.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a challenging complication resulting from the long-term application of bisphosphonates. In most cases, BRONJ occurs after a surgical procedure involving the jawbone. Currently, the management of BRONJ remains controversial, and there is no definitive treatment other than palliative methods.

The extent of chin ptosis and lower incisor exposure changes following the osseous genioplasties.

The incision and dissection of the mentalis muscles are inevitable to access the osteotomy line during genial surgery. As the mentalis muscles elevate the central lower lip and support the lip vertically, inadvertent scarring or lengthening of these muscles may lead to lip incompetence and may increase the lower incisor exposure (LIE) that will cause an unaesthetic result. The aim of this study was to evaluate the extent of lip ptosis, LIE, and other soft-tissue changes following different types of osseous genioplasty procedures.

Maxillomandibular fixation screws for early removal of hardware and correction of lingual tilting in alveolar distraction osteogenesis.

Alveolar distraction osteogenesis is a well-known technique used for the management of deficient alveolar ridges. Vector control of the transport segment is the main problem during distraction. This article describes a new technique for early removal of distractor and correction of tilted transport segment in partially edentulous patients.

Comparison of stability of resorbable and titanium fixation systems by finite element analysis after maxillary advancement surgery.

In this study, three-dimensional modeling and finite element analysis were used to evaluate and compare the stability of Le Fort I osteotomy fixed with titanium and resorbable fixation systems under molar and incisor bite forces. A three-dimensional model of 5-mm advanced hemimaxilla was generated. Contact analyses between the upper and lower segments were prescribed.
