Assessment of basal implants in compromised ridges

An Evaluation of the Efficacy and Acceptability of Basal Implants in Traumatically Deficient Ridges of the Maxilla and the Mandible

Background and objective Rehabilitation of edentulous jaw areas is a complex procedure that has witnessed numerous advancements in technique and materials for better functional and aesthetic outcomes over the years. Dental implants have emerged as a cutting-edge, cost-effective, and non-invasive alternative to traditional removable partial dentures (RPDs), fixed partial dentures (FPDs), and full dentures. In this study, the basal implant was tested in traumatically deficient ridges on the mandible and the maxilla to determine its effectiveness and acceptability. Materials and methods The purpose of this research was to determine whether basal implants might be successfully used to restore traumatized ridges in the maxilla and mandible. Eleven individuals aged 20-55 years participated in the trial, and a total of 30 implants were used. All patients were evaluated for pain, soft tissue health around the basal implant, and patient satisfaction, with follow-ups on the third day and at three and six months postoperatively. Results The mean pain score measured using the visual analog scale (VAS) of patients during follow-ups was 2.00 ±1.15 on the third day, 0.40 ±0.84 at three months, and 0.00 ±0.00 at six months postoperatively. The mean gingival index score of patients was 1.30 ±0.48 on the third day, 0.10 ±0.31 at three months, and 0.00 ±0.00 at six months postoperatively. The mean patient satisfaction score was 34.77±5.54 on the third day, 41.11 ±6.27 at three months, and 40.7 7±10.91 at six months postoperatively. The mean immediate postoperative marginal bone level was 12.33 ±2.26 mm, and it was 10.85 ±2.29 mm after six months postoperatively. The mean preoperative crestal bone level was 10.76 ±1.77 mm and it was 9.70 ±1.79 mm after six months postoperatively. Conclusion Due to the fact that basal implantology does not involve extensive augmentation procedures necessary for the placement of conventional implants, it plays an important role in the rehabilitation of edentulous maxillary and mandibular arches, especially in traumatic, moderate to severely atrophic maxillary and mandibular arches.

Esthetic Rehabilitation of a Young Patient With Immediately Loaded Single-Piece Basal Implants Following a Trauma Involving the Anterior Maxilla: Case Report With Five-Year Follow-Up

Traumatic injuries to the anterior maxilla usually lead to loss of teeth by means of avulsion or extraction due to fracture. Rehabilitation of such a clinical scenario is complex as it involves various anatomic and esthetic challenges. Single-piece basal implants have been widely used in the rehabilitation of resorbed ridges because they gain adequate anchorage from the basal cortical bone, allowing immediate temporization or loading. However, the use of basal implants in the anterior esthetic zone is not much documented. This case report with a five-year follow-up period describes the rehabilitation of lost teeth in the anterior esthetic zone of the anterior maxilla caused due to trauma following a train accident using single-piece axial basal implants with immediate temporization.

Single Tooth Replacement Using Immediately Loaded Basal Implant-Supported Fixed Prosthesis in a Hyperdense Lesion: A Case Report

Osseous modifications in the periapical areas are related to chronic endodontic infections. Often, teeth with periapical infections and hopeless prognosis are removed and replaced with dental implants. In this clinical report, a patient with a radiopaque lesion on the root apex of the mandibular right first molar root is presented. Bone- and tissue-borne lesions were the differential diagnoses for the radiopaque mass. Based on the clinical and radiological characteristics, condensing osteitis (CO) was the final diagnosis of osseous growth (bone density and trabeculation of the bone). Under local anesthesia, tooth 46 was atraumatically extracted, and the immediate basal implant was placed. This case report investigated the effectiveness and safety of dental implantation in the vicinity of hyperdense lesions.

Design of patient specific basal dental implant using Finite Element method and Artificial Neural Network technique

The bone conditions of mandibular bone vary from patient to patient, and as a result, a patient-specific dental implant needs to be designed. The basal dental implant is implanted in the cortical region of the bone since the top surface of the bone narrows down because of aging. Taguchi designs of experiments technique are used in which 25 optimum solid models of basal dental implants are modeled with variable geometrical parameters, viz. thread length, diameter, and pitch. In the solid models the implants are placed in the cortical part of the 3D models of cadaveric mandibles, that are prepared from CT data using image processing software. Patient-specific bone conditions are varied according to the strong, weak, and normal basal bone. A compressive force of 200 N is applied on the top surface of these implants and using finite element analysis software, the microstrain on the peri-implant bone ranges from 1000 to 4000 depending on the various bone conditions. According to the finite element data, it can be concluded that weak bone microstrain is comparatively high compared with normal and strong bone conditions. A surrogate artificial neural network model is prepared from the finite element analysis data. Surrogate model assisted genetic algorithm is used to find the optimum patient-specific basal dental implant for a better osseointegration-friendly mechanical environment.
