The mucosal released‐coronally advanced flap: A novel surgical approach—a case report
Full text linkBackgroundThe coronally advanced flap (CAF) can be a predictable surgical technique for the treatment of gingival recessions. However, the characteristics of the defect (e.g., limited amount of keratinized gingiva or flap tension, etc.) may limit the use of the CAF with a possible requirement of additional surgical interventions (i.e., the use of a tissue graft to be harvested from donor sites or connective tissue substitutes).MethodsA 28-year-old woman patient, with no history of periodontal disease, came for referral presenting receding gums as a chief complaint, poor esthetics, and dentinal hypersensitivity at the buccal surface of teeth 11, 12, and 13. Clinically, she presented a thick phenotype with gingival recession type, RT1, with detectable cemento-enamel junction (A-) in the second quadrant. To reduce the need of harvesting soft tissue grafts, the amount of cutting of muscles and vessels from the inner portion of the flap and mitigate the postoperative discomfort associated with the CAF, a novel surgical approach is described here using an advanced flap that incorporates an external incision along the mucogingival junction.ResultsThe average root coverage achieved with the novel procedure presented in this case report was 95%, along with an increased amount of keratinized gingiva and minimal postoperative patient's discomfort.ConclusionsThe mucosal released CAF is a promising technique in which the CAF technique alone may not be an indication.Key pointsThis technique has the following advantages: Reduce the need of harvesting soft tissue grafts. Reduce the amount of cutting of muscles and vessels from the inner portion of the flap. Minimal postoperative discomfort for the patient
The effect of hyaluronan on mouse intramembranous osteogenesis in vitro
No full textHyaluronan (HA) is an almost ubiquitous component of extracellular matrices. Early in embryogenesis mesenchymal cells migrate, proliferate and differentiate, in part, because of the influence of HA. Because many of the features of embryogenesis are revisited during wound repair, including bone fracture repair, this study was initiated to evaluate whether HA has an effect on calcification and bone formation in an in vitro system of osteogenesis. Enzyme-digested calvarial mesenchymal cells from 13-day-old mouse embryos were cultured in BGJb medium with rooster comb hyaluronan in seven different molecular weights (30, 40, 90, 160, 550, 660, and 1300 kDa). The dosages for each molecular weight were 0.5, 1.0 and 2.0 mg/ml. HA was added once to the medium at the plating of cells. After 10 days in culture, with low molecular weight hyaluronan (30 and 40 kDa) bone colonies were identifiable on a base of confluent fibroblasts. The number of colonies was larger than controls, particularly in the 1.0 and 2.0 mg/ml dosages of both 30 and 40 kDa of HA. Hyaluronan of high molecular weight, no matter what the dose, showed no significant bone colony formation, with apparent cell growth inhibition. Higher molecular weights were thereafter not included in this study. No statistically significant difference in the size of colonies was found when compared to controls in the 30 and 40 kDa bone colonies no matter what the dose
Temporary crowns: Repositioning key as a new technical approach in the clinical relining phase
No full textTo accomplish prosthetic rehabilitation, a series of important procedures must be followed to achieve the correct final prosthetic outcome. The protocol presented in this article proposes a different approach that involves relining the temporary crowns during the provisional phase by means of a repositioning key. This approach is especially useful for therapeutic provisional restoration in patients with temporomandibular joint disorders. CLINICAL SIGNIFICANCE The methodology presented allows the exclusion of arbitrary repositioning in the three-dimensional space of the provisional restoration, considering it as a fixed starting point. Our results tend to emphasize this technique not only for the ease of use, but also for the shorter time required for the occlusal fitting procedures in the final finishing phases
Laterally moved, coronally advanced flap for the treatment of a single Stillman's cleft. A 5-year follow-up.
No full textThe treatment of gingival recessions is one of the important branches of periodontics related to esthetics. However, no surgical technique has been reported for the treatment of a particular type of gingival recession called Stillman's cleft. The technique proposed is a laterally moved, coronally advanced flap. After local anesthesia, two parallel incisions, one along the cleft and the second parallel to the first one, have been placed beyond the mucogingival junction, allowing a rotating partial-thickness flap to cover the recession. The procedure, in this case presentation, resulted in successfully covering the previously exposed root surface. Root coverage of a Stillman's cleft can be obtained and maintained for 5 years follow-up with a laterally moved, coronally advanced flap.The treatment of gingival recessions is one of the important branches of periodontics related to esthetics.

No full textQualitative assessment of connective tissue graft with epithelial component. A microsurgical periodontal plastic surgical technique for soft tissue esthetics.
No full textConnective tissue grafts have been used successfully in the treatment of gingival recession. In the mid 80s and late 90s, the periodontal literature presented various techniques such as free gingival grafts, pedicle flaps, subepithelial connective tissue grafts, acellular dermal matrix grafts, and guided tissue regeneration to cover denuded root surfaces. Currently, connective tissue grafting is a reliable treatment for esthetic root coverage. This paper presents a qualitative assessment of a surgical technique that uses a connective tissue graft, including a portion of epithelium in the shape of the defect. This procedure enhances the healing of the covered root surface, increases the thickness of the soft tissue and improves esthetics. The criteria used for evaluation were: color, volume, texture, and blending. This evaluation demonstrated encouraging results from an esthetic viewpoint
