Dentoalveolar development in beagle dogs after palatal repair with a dermal substitute.

Introduction: Our aim was to compare the dentoalveolar development in beagle dogs after palatal repair according to the Von Langenbeck technique with and without implantation of a dermal substitute.

Methods: Nineteen beagles (age, 12 weeks) were assigned to 2 experimental groups and an untreated control group. Palatal surgery was performed with the Von Langenbeck technique in the 2 experimental groups.

Implantation of tissue-engineered mucosal substitutes in the dog palate.

Tissue shortage complicates the surgery of cleft palate (CP) anomalies. The healing of defects on the palate impairs growth of the dento-maxillary complex due to scar tissue formation. Implantation of grafts into the wound area might reduce this adverse effect of surgery.

Evaluation of a collagen-glycosaminoglycan dermal substitute in the dog palate.

Tissue shortage complicates surgery of cleft lip and palate. The healing of defects on the palate impairs growth of the dentoalveolar complex because of scar tissue formation. Implantation of a matrix into the wound might overcome this adverse effect.

Histologic evaluation of skin-derived and collagen-based substrates implanted in palatal wounds.

Tissue shortage complicates the surgery of cleft lip and palate anomalies and the healing of defects on the palate impairs growth of the dento-alveolar complex due to scar tissue formation. Implantation of substitutes into the wound area might overcome this adverse effect. The aim of this study was to compare the tissue response to three collagen-based (collagen type I substrate alone, or collagen coated with elastin or chondroitin-6-sulfate) and two skin-derived substrates (unprocessed dermis and AlloDerm) after implantation into 12 dogs.

Dental maturity in children with a complete bilateral cleft lip and palate.

Objective: Dental age in children with a bilateral cleft lip and palate (BCLP) was assessed and compared with children without cleft.

Design: Dental age was estimated for 74 children with a complete BCLP (54 boys and 20 girls) from 364 orthopantomograms. Nonlinear regression curves were made between 5 and 14 years of age for boys and girls separately.
