Treatment of donor site wounds using facial skin remaining in the scar area.

Reconstruction of cheek skin defects is surgically challenging. We evaluated the outcomes of using cheek skin remaining in the scar area for treating donor site wounds following the repair of cheek skin defects using full-thickness skin. We conducted a retrospective case series study that included 12 patients with a scar of the cheek.

Thread shape affects the stress distribution of torque force on miniscrews: a finite element analysis.

This study aimed to investigate the effect of miniscrews thread shape on the stress distribution receiving a torque load. Seven thread shapes (S,V1,V2,B1,B2,R1,R2) models were constructed and a 6 Nmm-torque load was applied. The order of maximum equivalent stress (EQV) value was V1 > V2 > B1 > R1 > R2 > B2 > S.

Vermilionectomy followed by reconstruction of the vermilion mucosa using allograft dermal matrix in patients with actinic cheilitis of the lower lip.

Background: When treating actinic cheilitis (AC), it is essential to minimize the risk of malignant transformation (MT) and maintain lip functionality and cosmesis.

Aims: We evaluated the outcomes of vermilionectomy followed by reconstruction of the vermilion mucosa using allograft dermal matrix (ADM) in patients with AC of the lower lip.

Materials And Methods: We evaluated eight patients with lower lip AC who underwent vermilion mucosa reconstruction using ADM after vermilionectomy.

Finite Element Analysis of Bone Stress around Micro-Implants of Different Diameters and Lengths with Application of a Single or Composite Torque Force.

Background: Stress on the bone surrounding dental micro-implants affects implant success.

Purpose: To compare the stress on the bone surrounding a micro-implant after application of a single force (SF) of 200 g or a composite force (CF) of 200 g and 6 N.mm torque.

Effect of heating palladium-silver alloys on ceramic bond strength.

Statement Of Problem: The effects of different heat treatments on the internal oxidation and metal-ceramic bond in Pd-Ag alloys with different trace elements require further documentation.

Purpose: The purpose of this in vitro study was to determine whether heat treatment affects the metal-ceramic bond strength of 2 Pd-Ag alloys containing different trace elements.

Material And Methods: Thirteen cast specimens (25×3×0.

Expression of Cyr61 in primary salivary adenoid cystic carcinoma and its relation to Ki-67 and prognosis.

Cysteine-rich protein 61 (Cyr61) selectively binds heparin and insulin-like growth factors and mediates a variety of biological actions, including cell adhesion, differentiation, proliferation, migration, angiogenesis, and tumorigenesis. Cyr61 is also a prognostic factor for tumor progression and survival of individuals with various types of tumors. This study investigated the relationship between the expression level of Cyr61 and clinicopathological features, as well as the prognostic significance of Cyr61 expression in human salivary adenoid cystic carcinoma (SACC).
