The field of periodontics has become increasingly discussed and advanced in recent decades. The techniques of periodontal soft tissue grafts are among these advancements. The techniques have been used more and more clinically not only in periodontics, but also in the areas of dental implantology, aesthetics, and orthodontics. In this article, we discuss the clinical indications and the advantages and disadvantages of several autogenous tissue grafts (e.g. pedical grafts, free gingival graft, and subepithelial connective tissue graft)...

Background: To overcome the limited source of autogenous bone in bone grafting, many efforts have been made to find bone substitutes. The use of hybrid composites of silk and hydroxyapatite to simulate natural bone tissue can overcome the softness and brittleness of the individual components. Methods: Critical-sized, 7 x 4 x 1.5 mm alveolar defects were created surgically in 36 Sprague-Dawley rats. Three treatment groups were tested: an empty defect group (group I), a silk fibrin scaffold group (group II), and a hydroxyapatite-conjugated silk fibrin scaffold group (group III)...

This case report describes a 55-year-old male patient with type II necrotizing fasciitis (NF) of the hand and forearm. The rapid progression of the tissue infection could be successfully stopped with radical surgical débridement and antibiotic therapy. For the reconstruction of the extensive loss of soft tissue a combination of split-thickness skin graft (STSG) and the synthetic dermal substitute MatriDerm® was used. In cases of NF, MatriDerm® and STSG provide a rapidly available and simple alternative to other reconstruction techniques...

BACKGROUND: When keratinized tissue width around dental implants is poorly represented, the clinician could resort to autogenous soft tissue grafting. Autogenous soft tissue grafting procedures are usually associated with a certain degree of morbidity. Collagen matrices could be used as an alternative to reduce morbidity and intra-operatory times. The aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants...

BACKGROUND: Anterior cruciate ligament (ACL) grafts that are placed for reconstruction are subject to complex forces. Current "anatomic" ACL reconstruction techniques may result in greater in situ graft forces. The biological effect of changing magnitudes of ACL graft force on graft-tunnel osseointegration is not well understood. PURPOSE: The research objective is to determine how mechanical force on the ACL graft during knee motion affects tendon healing in the tunnel...

Current approaches to orbit reconstruction are based on the assumption of facial symmetry and surgeons' experiences, and the reconstructed orbits are not precise. Through computer-assisted volumetric quantitative analysis, the volume of the bony orbit, and the volume of the soft tissues in both the anophthalmic orbit and the contralateral orbit are calculated in 39 anophthalmic patients. The rib graft is used for orbit reconstruction; the dosalis pedis flap and lipo-injection were used for soft tissue reconstruction and skin socket reconstruction...

Fei Wang, Pralab Pradhan, Ning Li, Canhua Jiang, Wen Liu, Lijuan Zeng
Extended anterolateral thigh (ALT) flap can provide a large amount of skin to reconstruct the extensively full-thickness defects of cheek. However when the width of 1 skin paddle exceeds 8 cm, it always results in that the donor site cannot be closed primarily and need to be covered by split-thickness skin grafting, which delivers lots of impacts on the functional and cosmetic outcome of the thigh. The aim of this study was to introduce the authors' modification of stacking 2 skin paddles of the tripaddled ALT flap to reconstruct the extensive full-thickness defects in the cheek after the radical ablasion of advanced buccal squamous cell carcinoma...

OBJECTIVES: Extraction socket preservation procedures are critical to successful esthetic implant therapy. Conventional surgical approaches are technique sensitive and often result in alteration of the soft tissue architecture, which then requires additional corrective surgical procedures. This case series report presents the ability of flapless surgical techniques combined with a growth factor-enhanced bone matrix to provide esthetic ridge preservation at the time of extraction for compromised sockets...
