ABSTRACT
Introduction: Preservation of alveolar dimensions after tooth extraction is crucial to achieve optimal esthetic and functionalprosthodontic results. With the increasingly frequent use of dental implants to replace non-restorable teeth, preservation ofthe existing alveolus is essential to maintain adequate bone volume for placement and stabilization of the implants. The aimof the study was to clinically and radiographically compare and evaluate autogenous dentin as bone graft with demineralizedfreeze-dried bone allograft (DFDBA) and extraction socket left alone for healing.Materials and Methods: Ethical clearance was obtained for the study. A written informed consent was taken from all theparticipants. A total of 45 randomly selected adult patients were divided into three groups: (1) Extraction socket with graftmaterial placement: Autogenous dentin (natural tooth dentin) as a bone graft (15 participants). (2) Extraction socket with graftmaterial placement: DFDBA as a bone graft (15 participants). (3) Extraction socket to be left alone for healing (15 participants).The cases were examined at 3, 6, and 9 months post-intervention. For each visit, clinical and radiographic assessmentradiovisiography was done to access the bone tissue healing. The mean buccolingual bone ridge width and height werecompared both clinically and radiographically. The data collected were subjected to statistical analysis using SPSS 22.0.ANOVA and paired t-test were carried out for comparing the mean bone buccolingually on the radiograph. All P < 0.05 wereconsidered to be statistically significant.Results: The mean buccolingual ridge width measured by Vernier caliper for the I group was 7.13 ± 0.91, for II group, it was6.20 ± 0.86, and for the III group was 5.33 ± 0.61. The difference between the groups was statistically significant at 9 months.The mean height of the bone measured by radiograph showed that for I group, it was 6.33 ± 0.88, for II group, it was 6.13 ± 0.83,and for the III group, it was 5.33 ± 0.61. The difference in the mean outcome was significant between I and III as well as II andIII groups.Conclusion: The results of the grafted sites showed statistically significant difference compared to non-grafted sites.The alveolar ridge preservation shows reduction in buccolingual shrinkage. The present investigation shows thataugmenting the extraction socket with biomaterials may have the possibility to limit the buccolingual and coronalapical shrinkage.
ABSTRACT
Success cannot be guaranteed, what one can guarantee is to care, to do one’s best, and to be there to help in the rare instance ifsomething goes wrong. Dental implants are most commonly used for the replacement of missing teeth. Lack of osseointegrationand peri-implantitis are considered as major contributory factors of implant failure. This case report presents a procedure andtreatment option for immediate implant placement into previously early failed dental implant osteotomy
ABSTRACT
Since the inception of implant dentistry, implant-supported metal-acrylic resin hybrid prostheses are the major prostheticdevices given to restore physiological and esthetic functions of oral tissues of edentulous or partially edentulous patients. Theclinical performance of the most commonly used acrylic resin in the fabrication of dentures, namely, polymethyl methacrylate(PMMA) resin determines its long-term deformation and wear resistance. However, its poor mechanical resistance to wearand tear poses a major setback. An attempt to incorporate graphene derivative with PMMA resin in prosthesis fabrication hasdemonstrated significant improvement in the mechanical strength as per literature. This case report presents rehabilitation ofedentulous mandibular jaw and also briefly states the properties of graphene and the polymerization process of the resin withthe graphene derivative.
