摘要:

The use of mandibular symphyseal bone in bony reconstruction of limited anterior defects is common. This communication suggests the use of a template to ensure accurate sizing of the graft. A technique is also suggested where the screw hole in the grafted bone is made prior to the removal from the donor site. These modifications greatly simplify the transfer of bone grafts in these cases.

摘要:

PurposeSystemic factors, such as diabetes mellitus, can influence the success rate of dental implants. The authors describe their experience using the MIS implant system (Medical Implant System, Shlomi, Israel) for retention of overdentures in patients with type 2 diabetes mellitus and provide data regarding the level of satisfaction of the patients, the improvement of function, mucosal and periimplant health, and bone level around implants in this group.MethodsThe study group consisted of 41 patients with type 2 diabetes mellitus who received 141 implants for retention of overdentures.ResultsThe success rate was 97.3% and 94.4% 1 and 5 years following implantation, respectively. The majority of patients reported improvement of function following the new treatment. A high correlation was observed between mucosal health and improvement of function. No correlation was found between failed implants and glucose level.ConclusionThe clinical outcome of dental implants in a selected group of patients with well-controlled type 2 diabetes mellitus is satisfying and encouraging. Further investigations and clinical trials over a longer period of time are needed to determine the long-term survival of implants in diverse groups of patients with diabetes mellitus.

摘要:

PurposeThis clinical report describes an immediate tooth extraction, followed by placement and provisional restoration of a dental implant in the prepared socket of a right maxillary central incisor.Materials and MethodsThe tooth was extracted with minimal hard and soft tissue trauma and without flap reflection. A flapless, transmucosal surgical approach was used to prepare the socket and insert a tapered implant. The implant was immediately restored with a provisional abutment and crown without occlusal contacts. An impression was made 22 days after implant insertion, and a definitive, all-ceramic restoration was placed 3 days later.ResultsDuring the period of provisional progressive loading, no significant soft tissue contraction was observed related to noninvasive operating techniques and the immediate insertion of the provisional restoration. The patient exhibited no clinical or radiologic complications through 8 months of clinical monitoring after loading.ConclusionThe Tapered Screw-Vent® implant and all-ceramic restoration provided the patient with immediate esthetics, function, and comfort without any complications during the postloading follow-up period.

摘要:

Le Fort I osteotomy is a versatile procedure in oral and maxillofacial surgery for the correction of dysgnathias as well as for an easy approach to the surgical site in neurosurgery; however, it is rarely performed for a vertical advancement of the maxilla. This paper presents the successful use of the synthetic pure-phase &bgr;-tricalcium phosphate (&bgr;-TCP) Cerasorb® (Curasan, Kleinostheim, Germany), together with autogenous bone at a ratio of 4:1, in combination with patients’ own platelet-rich plasma for a vertical augmentation of completely atrophied maxillae, resulting in an advancement of 16 and 14 mm, respectively. After a period of 8 months the &bgr;-TCP was completely resorbed and the x-ray control showed no residual granules in the defect sites. Pure-phase &bgr;-TCP proved to be a bone-regeneration material, providing the patient with vital bone at the defect site in a reasonable time, making a second surgical procedure for bone harvesting (eg, at the iliac crest) unnecessary. The relapse of approximately one third in the second case did not affect the success of treatment and was attributed to the combination of platelet-rich plasma with a resorbable polylactic membrane. Thus, in the combination of pure-phase &bgr;-TCP and platelet-rich plasma, the use of nonresorbable membranes and suture materials is recommended. These results encourage the qualified surgeon to use the pure-phase &bgr;-TCP for bone regeneration even when performing augmentations of this dimension.

摘要:

A case is reported of dental implant placement in a 13-year-old patient diagnosed with Papillon-Lefevre Syndrome. Two titanium dental implants were placed in the mandible for an implant-retained denture after the patient complained of having an unstable prosthesis. Follow-up radiographs showed successful osseointegration and preservation of alveolar bone 1 year after implant placement and the continual wearing of a functional dental prosthesis.
