Preservation of Peri-implant Soft and Hard Tissues Using Platform Switching of Implants Placed in Immediate Extraction Sockets : A Proof-of-Concept Study with 12- to 36-month Follow-up
No full textPURPOSE: The purpose of this article is to evaluate the soft and hard tissue response to immediately loading implants. In addition, the soft tissue response to a transmucosal abutment that is narrower than the implant platform was assessed.
MATERIALS AND METHODS: Ten consecutive hopeless teeth in the anterior maxilla without compromised bone tissue were enrolled. The infection control phase of periodontal therapy was completed. Immediately after tooth extraction, an implant was placed with a 6 mm platform diameter. A provisional 4 mm diameter transmucosal abutment was connected and a provisional crown was adapted and adjusted for non functional immediately loading. Three months following implant placement, definitive prosthetic rehabilitation was performed. At the time of prosthesis insertion (baseline) and every six months there after, radiographic assessments, pocket probing depths (PPD), recession (REC) and papilla height (PH) were measured. An image analysis software application was used to compare the radiographic bone remodeling at the mesial and distal aspects of the implants. The statistical significance was analyzed by the Student’s t-test with p<0.05.
RESULTS: Nine patients with ten sites were treated. Mean follow up time was 22 months with a range of 36 to 18 months. All the 10 implants were osseointegrated .
Software analysis of radiographic films showed a bone resorption of 0.78 mm (SD: 0,3690). The mean values were statically significant (p≤ 0,005) using a mean reference value of 1.1 mm.
PPD did not exceed 3 mm in any site (average: 2.8 mm). REC gain mean value was 0.2 mm and PH gain mean value was 0.25 mm.
CONCLUSIONS: Within the limit of this study, the data suggests that immediately loading with Platform Switching seems provide peri-implant hard tissue stability, with a consequent soft tissue stable profile

Surgical reinstatement of aesthetics in the maxillary anterior region: a case report
No full textThe maxillary anterior region is frequently treated for aesthetic enhancement. This article presents the case of a patient who had undergone surgery for treatment of a tumor of the hypophysis involving intraoral access to the sella turcica. The treatment had caused the formation of severe gingival recession on the buccal surface of the maxillary anterior teeth. A variety of surgical techniques were considered for covering the exposed root surfaces. The surgical site was analyzed, and the response of the periodontal tissue to the treatment was anticipated. The bilaminar method, utilizing a subpedicle connective tissue graft (SCTG), was selected. The learning objective of this case presentation is to demonstrate that when the appropriate treatment procedure is selected, restoration of function and aesthetics can be achieved even in the most advanced cases
Surgical technique for treatment of infrabony defects with enamel matrix derivative (Emdogain): 3 case reports
No full textA surgical protocol is described for the placement of Emdogain enamel matrix derivative during new attachment procedures. Three cases with infrabony defects were treated and a significant probing attachment level (PAL) gain, probing depth reduction, and bone fill were evident on clinical probing and during reentry procedures. The first patient presented a combined one-walled and circumferential defect at a maxillary central incisor. After 1 year the PAL gain was 7 mm. The second case showed a 3-walled defect distal to a maxillary canine. After 1 year the PAL gain was 8 mm, and a reentry procedure showed an almost total fill of the defect. The third patient presented a combined one- and 3-walled defect in the most apical part of the mesial aspect of a maxillary central incisor. One year after the surgical procedure, an orthodontic treatment was performed in this patient. After 6 more months the soft tissue showed a very good esthetic appearance, the papilla height was fully maintained, and there was a PAL gain of 5 mm; 18 months after surgery, reentry showed a significant regeneration of hard tissue that was impossible to probe. Because of these encouraging clinical results, further studies should be initiated to investigate the efficacy of the enamel matrix derivative in new attachment procedures
