Pedicled buccal fat pad flap for upper lip augmentation in orthognathic surgery patients.

Purpose: In this article, a new method of upper lip augmentation using a bilateral buccal fat pad flap is reported. This prospective study evaluated the changes in the upper lip that occur after maxillary surgery with concomitant mobilization of the bilateral buccal fat to improve upper lip projection.

Materials And Methods: A bilateral pedicled buccal fat pad flap to fill the premaxilla, paranasal, and upper lip areas, in association with a Le Fort I osteotomy for maxillary advancement, was performed in 11 orthognathic surgical patients with a thin upper lip.

5-year clinical experience with BTI dental implants: risk factors for implant failure.

Objectives: The aims of this study were to identify with appropriate statistical tests the risk factors associated with implant failure and to evaluate the long-term survival of dental implants using implant loss as an outcome variable and performing an implant-, surgery- and patient-based analysis of failures.

Material And Methods: A retrospective cohort study design was used. One thousand sixty patients received 5787 BTI implants during the years of 2001-2005 in Vitoria, Spain.

Autologous platelets as a source of proteins for healing and tissue regeneration.

Platelets are known for their role in haemostasis where they help prevent blood loss at sites of vascular injury. To do this, they adhere, aggregate and form a procoagulant surface leading to thrombin generation and fibrin formation. Platelets also release substances that promote tissue repair and influence the reactivity of vascular and other blood cells in angiogenesis and inflammation.
