Assessment of Frequency on Bone Grafting in Anterior Maxilla During Implant Placement

Abstract Endosseous implants are the treatment of choice for restoring function and reconstructing most edentulous areas of the maxilla and mandible. In general, alveolar bone defects can be reconstructed by either distraction osteogenesis or autogenous bone grafting. After alveolar reconstruction, endosseous implants are used to support and retain the prosthesis for restoration of form and function. Eighty-two consecutive patients requiring alveolar augmentation prior to implant placement were evaluated. All patients were given treatment options for reconstructing their alveolar defects, which included autogenous bone grafting vs distraction osteogenesis. Sixty-five patients received autogenous grafts (anterior iliac crest: 44; retromolar: 17; tibia: 2; chin: 2), and 17 patients underwent distraction osteogenesis prior to implant placement. A total of 184 implants were placed in the autogenous bone-grafted sites and 56 implants in the distracted bone sites. Implants placed in sites restored with autogenous bone grafts had an implant success rate of 97% (178/184), whereas implants placed in distracted bone sites had a success rate of 98% (55/56). In the autogenous grafted group, 3 implants failed in the posterior mandible, one in the anterior maxilla, one in the anterior mandible, and one in the posterior maxilla. In the distraction group, one implant failed in the posterior mandible. Both techniques are associated with good success rates. There was no statistical difference between implant success in autogenous bone vs distracted bone sites in this group of patients.

Posterior Maxilla

Atrophic edentulous anterior maxilla is a challenging site for implant placement and has been successfully treated surgically by anterior maxillary osteoplasty. This procedure is associated with considerable discomfort, morbidity, and cost—and consequently reduced patient acceptance. The efficacy and safety of minimally invasive bone augmentation of the posterior maxilla has not been extended thus far to the anterior subnasal maxilla. We present 2 representative cases in which minimally invasive subnasal floor elevation was performed along with minimally invasive antral membrane balloon elevation. Both segments underwent bone grafting and implant placement during the same sitting. Minimally invasive anterior maxilla bone augmentation appears to be feasible. Designated instruments for alveolar ridge splitting and nasal mucosa elevation are likely to further enhance this initial favorable experience.

Multicenter Clinical Study

The purpose of the study was to evaluate survival and peri-implant bone levels of single, immediately loaded post-extractive implants in the anterior maxilla 12 months after implant placement. Thirty-six consecutive patients from 3 study centers were included in the study. The concerned sites were upper premolars, canines, and incisors. For each patient the following data were recorded: reason for tooth extraction, bone quality, implant size, and final insertion torque. Implants were placed using a flapless technique and immediately loaded with a nonoccluding temporary restoration. Final restorations were provided 4 months later. Peri-implant bone resorption was evaluated radiographically after 6 and 12 months. The average final insertion torque was 70.55 Ncm. One implant inserted in D3 quality bone with a 35-Ncm seating torque was lost. All other implants had a final insertion torque ranging between 50 and 80 Ncm. The average peri-implant bone loss was 0.437 and 0.507 mm at 6 and 12 months, respectively. All the sites maintained excellent papillae and peri-implant soft-tissue conditions. The resulting 1-year success rate was 97.2%. Immediate nonfunctional loading of single post-extractive implants in the anterior maxilla is a predictable treatment. And it seems that achieving high insertion torques by placing self-tapping/self-condensing implants in an underprepared osteotomy is favorable.

Variable Clinical Presentation

Traumatic oral injuries present their own unique restorative challenges to the clinician due to their variable clinical presentation. In such cases, achieving optimum aesthetics and function in the maxillary aesthetic zone is challenging. This case report describes the rehabilitation of a patient with immediate implant placement after suffering trauma to the oral cavity resulting in a complete loss (avulsion) of a permanent central incisor tooth. In order to preserve the existing soft and hard tissue and to achieve predictable and aesthetically pleasing results, we decided to place an immediate implant as opposed to replantation of the avulsed tooth. Flapless implant surgery was planned and a dental implant (Bio horizons Implant Systems, Inc.) was placed following non-submerged protocol. At six month’s follow-up, the clinical and radiographic examination revealed a well osseo-integrated implant with an intact buccal cortical plate. Continuous...

Fixed Prosthesis

Fresh frozen allograft bone is routinely used in orthopedic surgery for the reconstruction of large bone defects, and its use in oral and maxillofacial surgery is increasing. The purpose of this case was to demonstrate the installation of dental implants and the use of fresh frozen bone for reconstruction of anterior maxilla in the same surgery. This case report presents the insertion of dental implants followed immediately by a placement of fresh frozen allograft in block and particle for a reconstruction of atrophic anterior maxillary in the same surgery. Ten months subsequent to this procedure, provisional fixed prosthesis was installed on the implants. Four months later (postoperative month 14), the final fixed prosthesis was installed and the clinical success was observed. The insertion of dental implants followed immediately by a placement of fresh frozen allograft is a safe and efficient process that results in the successful return of dental function and aesthetic rehabilitation for the patient.
