Purpose: Endosseous titanium dental implants are widely regarded as the gold standard for replacing missing teeth. Despite the proven osseointegration of titanium implants, particularly those with enhanced surface modifications, concerns remain regarding esthetics, the risk of peri-implantitis, and potential hypersensitivity. Consequently, alternative materials, such as zirconia, have received increasing attention in recent years. This study evaluated the osseointegration parameters of zirconia implants placed in the mandibles of beagle dogs, as a preliminary in vivo evaluation of zirconia dental implants in South Korea. Materials and Methods: Seven 8-month-old beagle dogs underwent premolar extraction followed by placement of implants in the healed mandibular ridges. The following implants were used in this study: six turned-surface titanium implants, six rough-surface titanium implants, and six zirconia implants, following which the implants and surrounding tissues were harvested en bloc for histological analyses. Bone-to-implant contact (BIC) and new bone area (BA) percentages (%) were calculated and compared between the groups. Statistical analyses were conducted using ANOVA, with the significance level set at p < .05. Results: Histological analysis revealed no statistically significant difference in BIC between the rough-surface titanium and zirconia implants, although the turned-surface titanium implants exhibited significantly lower BIC than the other two groups (p < .05). No significant differences were found among the three groups in terms of BA. Conclusion The results of this study demonstrate that zirconia implants achieve BIC comparable to that of rough-surface titanium implants, suggestive of their potential clinical application.

With the development of digital dentistry, it is being applied in various ways of dental treatment. This case report presents the definitive prosthesis designed in advance with a re-established vertical dimension and the digital technology, which determined the amount of tooth preparation, in order to preserve as much tooth structure as possible in a patient with pathological wear of the posterior teeth and loss of vertical dimension. For accurate tooth preparation, the guides of the occlusal and axial surfaces were digitally and additively manufactured. Then, aesthetics and anterior guidance were established at the provisional stage. The information of the provisional restoration was delivered to the definitive stage by double scanning. The digital technology, including the virtual planning and the guided tooth removal, produced the definitive restorations satisfactory to both the patient and clinician.

Installation of dental implants at optimal angles and positions is critical in longterm stable implant-supported restorations. Surgery and prosthodontic procedures should be performed accurately as the treatment is planned. In this clinical case, Computer aided design and manufacturing technology was used not only to establish a precise surgical plan, but also to fabricate both provisional and definitive fixed prostheses. A surgical guide was designed to install the implants at proper positions for the definitive prostheses. The patient’s esthetic information, which was necessary for the new provisional and definitive fixed prostheses, was obtained from the existing temporary dentures. Finally, the complete mouth fixed implant-supported rehabilitation using monolithic zirconia provided the patient with functionally and esthetically satisfactory prostheses.

PURPOSE: . This in vitro study aimed to evaluate the surface characteristics of a full veneer crown fabricated chairside (CS) from a (Y, Nb)-TZP zirconia block in response to conventional zirconia grinding and polishing. MATERIALS AND METHODS: . Zirconia crowns (n = 40) were first prepared and divided into two groups of materials: Labside (LS) and CS, after which each specimen went through a five-step grinding and polishing procedure. Following each surface treatment, surface characteristics were analyzed using confocal laser microscopy (CLSM), average surface roughness (Ra) values were processed from the profile data through Gaussian filtering, and X-ray diffraction pattern analysis was performed to evaluate the monoclinic (M) phase content. Then, a representative specimen was selected for field-emission scanning electron microscopy (FE-SEM), followed by a final analysis of the roughness and X-ray diffraction of the specimens using the independent t-test and repeated measures analysis of variance (RM-ANOVA). RESULTS . In every group, polishing significantly reduced the Ra values (P < .001).There was no significant difference in Ra between the polished state CS and LS.Furthermore, CLSM and FE-SEM investigations revealed that even though grain exposure was visible in CS specimens throughout the as-delivered and ground states, the exposure was reduced after polishing. Moreover, while no phase transformation was visible in the LS, phase transformation was visible in CS after every surface treatment, with the M phase content of the CS group showing a significant reduction after polishing (P < .001). CONCLUSION. Within the limits of this study, clinically acceptable level of surface finishing of (Y, Nb)-TZP can be achieved after conventional zirconia polishing sequence.
