Implant Treatment

Tooth loss among adults is associated with progressive periodontitis. Implant prosthetic treatment has long been utilized in periodontal patients. Even when the implants are applied, ongoing management of periodontal disease and control of inflammation is necessary to maintain a healthy oral cavity. Lack of appropriate periodontal treatment can result in recurrence of periodontal disease during a maintenance period; loss of the supportive capacity of the periodontal tissues will increase the susceptibility of residual teeth to traumatic force. For this reason, it is worthwhile to improve oral function by applying implants as a fixed device. Here, we report that implant treatment in a patient with generalized severe chronic periodontitis helped maintain the periodontal and peri-implant tissue for a long term. We propose that initial periodontal treatment and ongoing supportive therapy can help maintain implants in patients with severe periodontitis. In addition, we reviewed case reports in the English literature so far.

This article addresses diagnostic parameters that should be assessed in the treatment of extraction sockets with dental implant placement by presenting three case reports that emphasize the relevance of the amount of remaining bone walls. Diagnosis was based on the analysis of clinical and radiographic parameters (e.g.: bone defect morphology, remaining bone volume, presence of infections on the receptor site). Case 1 presents a 5-wall defect in the maxillary right central incisor region with severe root resorption, which was treated with immediate implant placement. Cases 2 and 3 present, respectively, two- and three-wall bone defects that did not have indication for immediate implants. These cases were first submitted to a guided bone regeneration (GBR) procedure with bone graft biomaterial and membrane barriers, and the implants were installed in a second surgical procedure. The analysis of the preoperative periodontal condition of the adjacent teeth and bone defect morphology is extremely important because these factors determine the choice between immediate implant or GBR treatment followed by implant installation in a subsequent intervention.

Implant Treatment

With the advancement in the dental implant treatment, many new innovative improvements have been developed in the designs and components of implants. These improvements helps to handle the compromising situations where sometimes the good treatment option can become more challenging. One of the such grueling condition is implant placement in the anterior maxilla where dentist has to fulll both aesthetic and functional demand. Many aesthetic failures of implant have been reported in the literature in the anterior maxilla. One of them is placing implant in sites with deciency of facial bone thickness which sometimes resulted in malposition of implant. This case report discusses about the prosthodontic correction of malpositioned implant in the anterior maxilla by using castable abutment. The use of castable abutment is concluded as successful treatment option for complex misaligned and malposed single dental implant.

Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from “benign vasoformative neoplasms” to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.

This is the first comprehensive review of the classification, preventative measures, diagnosis, treatment methods, and determination of success criteria of buccal bone plate fenestrations (BPFs) secondary to posterior implant surgeries. The purpose of this review is to present and discuss the current literature from peer-reviewed journals, recent studies, and international implantology guidelines and to provide practitioners with guiding points to identify and understand whether BPFs are complications or accidents of implant surgeries. In addition, this review sets forth a detailed set of criteria for the evaluation and diagnosis of BPFs and for the subsequent classification of BPFs as either complications or accidents of posterior implant surgeries. From the literature analyzed, it is clear that BPFs are disqualified from the class of implant treatment failures because BPFs neither impair nor significantly delay treatment. A comprehensive outline of preventative measures and surgery aids to avoid fenestrating the buccal bone plate during implant placement, and a variety of repair methods are included in this review. Considerations of treatment outcomes and patient sensitivities are also included in this comprehensive review.

Implant Treatment

To perform safe implant treatment, the anatomical structure and bone quality at implant placement sites are evaluated based on a patient's computerized tomography (CT) data, but there is no definite method to determine placement sites and the appropriate number of implants. The objective of this study was to investigate the influence of the number and arrangement of implants on the stress distribution in 3-unit posterior fixed partial dentures for the posterior mandible by mechanical analysis using the finite element method. Three-dimensional finite element analysis models were constructed from the CT data of a patient with missing mandibular teeth (Nos. 35, 36, 37). Implant placement was simulated under various conditions. Superstructures were connected and fixed with a titanium frame. As the loading conditions, 400 N vertical and lateral loads (45° on the lingual side and 45° on the buccal side) were applied to the upper areas of Nos. 35, 36, and 37, and the stress distribution and frame displacement were evaluated. When a vertical force was applied, no difference of the von Mises stress was noted among the 5 experimental conditions. When lateral force was applied from the lingual and buccal sides at 45°, the stress was higher than that induced by vertical force under all conditions, and it was especially high under mesial and distal cantilever conditions. When displacement of the titanium frame was measured, the displacement caused by lateral force was greater than that due to vertical force. In addition, comparison between long and short distal cantilever bridges revealed that displacement of the titanium frame tended to be smaller when the short cantilever was used. These findings suggested that the stress on peri-implant tissues and displacement of the titanium frame vary depending on the configuration and number of implants, with greater stress and more marked displacement of the titanium frame being induced by lateral force when the number of implants is reduced and a cantilever bridge is selected.

ABSTRACTDue to the angulation of maxillary bone as the maxillary bone resorption occurs from a buccal to palatal direction, bucco-lingually tilted implant placement is more likely especially in the posterior maxilla. The aim of this paper was to present a case restored by using a maxillary hybrid denture using Cresco method. A 59-year-old woman with an edentulous maxilla and five missing mandibular teeth was referred for implant treatment. Six months after sinus lift operation, four mandibular implants and six maxillary implants were placed. Due to the bucco-lingual tilt of two implants, the Cresco method was chosen to fabricate the metal framework for the maxillary hybrid denture that was delivered four months after implant placement. The main advantages of the Cresco method are a perfectly passive framework fit and corrected screw access holes. All ten implants placed were considered successful at 1-year recall, and no screw access holes were seen in the buccal part of the maxillary acrylic teeth.It was concluded that such screw-retained maxillary hybrid denture using the Cresco method met the esthetic expectations of a highly demanding patient.
