Comparative host response of 2 human acellular dermal matrices in a primate implant model.

Eplasty 2014 31;14:e7. Epub 2014 Jan 31.

LifeCell Corporation, Bridgewater, NJ.

Objective: We examined the differences in capsule formation between 2 commercially available human acellular dermal matrices in a nonhuman primate model.

Methods: Primates were implanted dorsally with a subcutaneously placed tissue expander and randomized into 3 groups, receiving skin coverage only, coverage with non-irradiated freeze-dried human acellular dermal matrix, or coverage with gamma-irradiated human acellular dermal matrix. After 9 weeks, soft tissue around the tissue expander was excised and evaluated qualitatively and quantitatively to assess extent of inflammation (CD68 antibodies and interleukin-6 levels), degradation and fibrosis (matrix metalloproteinase-1 and procollagen-1 staining), and mechanical (tensile) strength.

Cell Tissue Bank 2014 Sep 4;15(3):297-305. Epub 2013 Sep 4.

Faculty of Dentistry, SEGi University, No.9, Jalan Teknologi, Taman Sains Selangor, Kota Damansara, PJU 5, 47810, Petaling Jaya, Selangor, Malaysia,

As esthetics gain importance, periodontal plastic surgical procedures involving soft tissue grafts are becoming commoner both around natural teeth as well as around implants. Periodontal soft tissue grafts are primarily used for the purpose of root coverage and in pre-prosthetic surgery to thicken a gingival site or to improve the crestal volume. Soft tissue grafts are usually harvested from the palate. Read More

Custom porous polyethylene implants for large-scale pediatric skull reconstruction: early outcomes.

J Craniofac Surg 2012 Jan;23(1):67-70

Division of Plastic Surgery and Department of Oral Biology, University of Pittsburgh, Children's Hospital of Pittsburgh of UPMC, Pittsburgh, Pennsylvania 15201, USA.

Background And Purpose: Some of the most problematic craniofacial injuries in pediatric plastic surgery are large calvarial defects in children who have passed the age of maximal dural osteogenic potential and yet are too young to yield split calvarial grafts. Porous polyethylene (Medpor; Porex) is an alloplastic material that can be customized to precisely match a cranial defect. We present a clinical series that demonstrates successful use of porous polyethylene cranioplasties in large pediatric cranial defects. Read More

Immediate implantation with ridge augmentation using acellular dermal matrix and deproteinized bovine bone: a case report.

Authors:
Jun-Beom Park

J Oral Implantol 2011 Dec 6;37(6):717-21. Epub 2010 Aug 6.

Department of Molecular Medicine and Biopharmaceutical Sciences, Seoul National University, Seoul, Korea.

Immediate implant placement combined with hard and soft tissue grafting has been suggested because it may preclude dramatic postextraction bone loss and may decrease overall discomfort with reduction in the number of surgeries and in treatment time. In this case report, the acellular dermal matrix was used as a membrane for immediate implantation via a bone augmentation procedure in an esthetically challenging situation. The author suggests that this surgical technique provides the clinician with an option for an immediate implant therapy when primary closure is not intended. Read More

Moawia M Kassab

Clin Cosmet Investig Dent 2010 17;2:101-7. Epub 2010 Sep 17.

Division of Periodontics, Marquette University, School of Dentistry, Milwaukee, WI, USA.

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon.

Facial Plast Surg 1999 ;15(1):3-12

Division of Otolaryngology, University of Alabama School of Medicine, 1501 5th Ave., S. Birmingham, AL 35233, USA.

The features of the nose, mentum, and malar complex define a person's profile and give the essence of character to the visage. Whether profile deficiencies are due to congenital, traumatic, or aging factors, facial plastic surgeons are able to meet patients' and their own exacting demands more thoroughly with skeletal implants. Although the search for the perfect implant continues, today's armamentarium of implant materials is vast and, with appropriate selection and attention to technique, facial skeletal implants can be successful in creating change impossible to obtain with soft tissue techniques alone.

Int J Oral Maxillofac Implants 2001 Nov-Dec;16(6):875-9

Department of Periodontology and Oral Biology, Goldman School of Dental Medicine, Boston University, Massachusetts, USA.

The success of bone grafting procedures depends largely on the management and integrity of the gingival flaps. Soft tissues aid in the protection of the bone graft, participate in the revascularization of the newly formed hard tissues, and play an important role in the esthetic outcome of the reconstructive phase. Acellular dermal matrix (ADM) is a material obtained from human skin and used in plastic and reconstructive surgery as an allograft. Read More
