“…Living bone property is viscoelastic, but this has not been considered in previous dental implant studies. 19,21 Conclusions (i) For any patient-specific bone conditions and mandible sizes (bone height and width), the optimum basal dental implant design to achieve an osseointegrationfriendly mechanical environment at peri-implant bone has been established. (ii) 25 optimal basal dental implant models are designed and virtually implanted in the bone's cortical region and analyzed.…”

“…The dimensions of the basal dental implant are taken from various literature. 19,21 The abutment part of the basal dental implant is exposed in the oral cavity region, and the length is 5 mm. 56 Next to the abutment lies the neck region, which allows the basal dental implant to bend.…”

“…13 Finite element analyses 14 are used for determining the stress and load-bearing capacity on the dental bone, and it is observed that penurious transfer of load, misplacement of the dental implant, 15 improper geometry of implant, 16 primary and secondary stability of implant 17 are some of the factors that affect implant failure. As a result, patient-specific bone-friendly 18 dental implants are designed which include multiple design variables 19 like diameter, length of the implant, 20 supply of blood to tissues, 21 the primary stability, 22 mobility, 23 and quality of bone 24 that are checked at the time of placement of the implant. It is well-known that lot of care should be taken while placing the dental implant in the basal bone.…”

“…According to the available literature, the initiative was taken to design the traditional dental implants at using a FE analysis and ANN model considering the patient's bone condition and other design parameters. 19,21 This type of initiative was not given proper attention regarding basal dental implant using the aforementioned techniques and parameters like bone condition.…”

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.

Objectives Assessment of the clinical performance of a porcine dentin-derived particulate bone graft material for bone regeneration after tooth extraction with implant placement at 4 months, in comparison to a commercially available porcine bone-derived graft. Material and methods This study was a randomized, parallel-group, semi-double-blinded clinical trial evaluating the clinical safety, tolerability, and performance of Ivory Dentin Graft™ in comparison with a commercial bone-derived material in alveolar ridge preservation following tooth extraction (registered at ClinicalTrials.gov, May 12th, 2017, Identifier NCT03150472). Extraction sites were grafted with test or comparator material and a titanium implant placed at 4 months after taking a graft site biopsy. Primary endpoints were the extent of new bone growth and bone-graft integration at 4 months. Results The dentin graft material had statistically significantly more new bone formation (60.75% vs 42.81%, p = 0.0084, N = 20 vs 16), better bone-graft integration scores (good integration in 85% vs 40%, p = 0.0066), and higher mean radiodensity of the bone (981.5HU vs 727.7HU, p = 0.0011) at the graft site compared to the bone-derived material. The mean implant insertion torque force was similar for the dentin and bone materials (34.75 Ncm vs 34.06 Ncm). Titanium implant placement was successful in 95% of patients with the dentin graft material compared to 81.25% for the bone graft. Both materials had similar clinical safety and tolerability as determined by adverse events and local site reactions. Physician-assessed ease of grafting and ease of implant placement on a 10-point scale showed no statistical differences (8.78 vs 8.27, p = 0.2355; 8.05 vs 8.75, p = 0.1118, respectively). Conclusions A porcine dentin-derived bone graft material has clinical safety, tolerability, and performance for implant placement at 4 months after tooth extraction at least as good as a commercial bone-derived material. Clinical relevance The availability of porcine dentin-derived bone graft material allows wider use of dentin-derived material which has so far only been available in the form of autologous dentin from the patient’s own teeth.

Prosthetic rehabilitation with implant-supported fixed prosthesis in a completely edentulous patient: A clinical report

To present clinical strategies for prosthetic rehabilitation of completely edentulous patients using immediate-loading basal implants. A 58-year-old female patient was referred to the Department of Prosthodontics for restoration of her completely edentulous maxilla and mandible with a fixed full-arch implant-prosthetic rehabilitation. Since the patient lacks adequate bone in the posterior maxilla and is not willing to undergo a removable interim prosthesis, an immediate loading protocol along with 8 single-piece basal implants, including 2 pterygoid implants in the maxillary arch and 6 single-piece basal implants in the mandibular arch, was selected as the treatment option, followed by an acrylic provisional restoration. Four months later, a definitive fixed implant-supported prosthesis was delivered. This treatment strategy may be considered for rehabilitating patients with atrophic ridges demanding fixed provisional prostheses throughout the healing period and can be employed even in immediate implant placement after extraction.
