The aim of this study is to investigate the in vivo behaviour of five different biodegradable films after submucoperiosteal implantation on the palate of Beagle dogs. Non-porous films of poly-(L-lactic) acid (= PLLA), high molecular weight poly-(L-lactic) acid (= HMW-PLLA), poly-(DL-lactic) acid (= PDLLA), poly(~-caprolactone) (= PCL) and a copolymer of poly hydroxybutyrate 80% hydroxyvalerate 20% (= PHB-co-HV 80/20) were implanted submucoperiostally on the palate of Beagle dogs. After 2, 4, 8 and 12 weeks in situ, the structure of the films and the tissue reactions were studied histologically. In terms of mechanical properties and tissue response, the PHB-co-HV film is the most suitable for use on dogs.

“…Apart from the timing of surgical repair, iatrogenic morphological changes of palatal mucoperiosteum after surgery seem to be of importance in causing the adverse effects after surgery (Kremenak, 1984;Wijdeveld et al, 1989). Wijdeveld et al (1991) observed that, after palatal surgery in Beagle dogs, newly formed scar tissue in the former denuded bony areas was firmly attached to the underlying bone by means of Sharpey's fibers and lacked elastic fibers.…”

“…The collagen fibers of the scar tissue were organized into thicker bundles, oriented in a transverse direction, and periodontal fibers, fanned out into the scar tissue. The different properties of the scar tissue presumably cause a changed stress distribution during eruption of permanent teeth, resulting in unfavorable maxillary arch dimensions (Wijdeveld et al, 1989).…”

The effect of low-level laser treatment on maxillary arch dimensions after palatal surgery was investigated in Beagle dogs at an age of 12 weeks. A total of 30 dogs was used, and they were assigned to either a control group (Group C, n = 6) or one of two experimental groups (Group L, n = 12; and group LL, n = 12). After Von Langenbeck's palatal repair in the two experimental groups, denuded bony areas in the LL group were irradiated with a continuous Ga-As-Al laser beam (830 nm) and energy output set at 30 mW. A dosage of 1 J/cm2 wound surface area was used. Treatment was carried out three times a week, with a total of ten treatments. The animals of the L group served as non-treated control animals. Dental casts were made of all animals of all groups at regular intervals until they reached 25 weeks of age. Maxillary arch dimensions were studied. Dental arch dimensions in the deciduous dentition of both experimental groups were not disturbed by surgery, but after eruption of permanent teeth, mainly transverse maxillary arch dimensions in the premolar region increased less in both experimental groups than in the control group. It was concluded that low-level laser treatment under the conditions used in this study did not decrease the adverse iatrogenic effects of palatal surgery on maxillary arch dimensions.

“…In the studies of Wijdeveld et al(1989;1991), palatal surgery according to von Langenbeck technique was simulated in beagle dogs and resulted in inhibition of the growth and development of dento-alveolar structures. They attributed this result to: (1) the initial wounds construction, (2) the firm attachment of scar tissues to the palatine by means of Sharpey's fibers, (3) no elastic fibers demonstrated in the healing tissue, and (4) periodontal fibers being fanned out into the scar tissues.…”

Abstract:Objective: This study aimed to explore the effects of different types of palatal lateral excisions on the growth and development of the maxilla and dental arch, and to investigate the underlying mechanisms. Methods: A total of 112 3-week-old Sprague-Dawley (SD) male rats were randomly divided into a control and 3 experimental groups: the mucoperiosteal denudation group, the mucosal flap excision group, and the periosteum excision group. In the experimental groups, bilateral mucoperiosteal, mucosal flap and periosteum were excised respectively in the lateral one half of the palate. Four rats in each group were randomly chosen for sacrifice every two weeks. The maxilla was dissected following the excision. The widths of the maxilla and dental arch were measured and the histological phenomena were investigated at different phases. At the same time, 12 animals in each group were sequentially injected with calcein every two weeks. Three animals in each group, whose fluorescent labeling was used, were sacrificed for investigating bone formation at Week 8 following injection. Results: (1) Each experimental group presented the constriction of the maxilla and dental arch. The upper first molars in the experimental groups inclined medially. The mucoperiosteal denudation group showed the largest degree of effect followed by the periosteum excision group. The indices of the mucosal flap excision group, which retained the structures of the periosteum layer, had the most approximate values to the control group; (2) Different histological changes among the experimental groups were detected. The fibers penetrated into the palatal bone as Sharpey's fibers in the mucoperiosteal denudation group. The pattern of bone deposition was the bundle type. Sharpey's fibers were not found in the mucosal flap and periosteum excision groups and the depositions of palatal bone were the lamellar type as those in the control group; (3) The rates of bone deposition in the experimental groups decreased compared with the control group. The rates in different phases were the most approximate values to those of the control group in the mucosal flap excision group, which has the same structure of periosteum as the control group. Conclusion: There were different effects on the growth and development of the maxilla and dental arch in different types of palatal lateral excisions. Periosteum is important for bone formation and deposition pattern. The prevention of Sharpey's fibers forming and attaching to the palatine can effectively avert the following malformation.
