Introduction: Nowadays, the final success of implantation is not only based on obtaining osseointegration of the implant but is also determined by achieving a satisfactory aesthetic effect of the soft tissues surrounding the implant, which can be defined as an aesthetic integration. The process of obtaining this aesthetic integration already begins at the stage of placing the healing abutment, which allows us to obtain the emergence profile necessary for our prosthetic reconstruction. Materials and Methods: The study used cone-beam computer tomography (CBCT) scans of 51 patients. The measurements of the maxillary teeth (central incisor, lateral incisor, canine, first premolar, and first molar) were performed from cross-sections of the individual teeth at the transition zone to design a custom anatomic healing abutment milled from zirconium and luted to the non-index Ti-base. Results: The obtained results allowed to design and create the shape of the anatomic healing abutment. Conclusions: The use of laboratory-produced anatomical healing abutments is possible and may allow to obtain the desired and planned emergence profiles of prosthetic restorations. In addition, it might be a method of reducing work time at the dental chair but further clinical trials are necessary.
Background: Medication-Related Osteonecrosis of the Jaws (MRONJ) is a serious complication of antiresorptive therapy. The aim of the study was to assess the level of knowledge and awareness regarding MRONJ among Polish dentists and students of dentistry. Methods: The online self-administered questionnaire was sent out electronically among dentists in Poland and dentistry students of the Medical University of Gdansk. The results obtained were statistically analyzed. The results were considered statistically significant if the condition p ≤ 0.05 was met. Results: A total of 203 respondents participated in this survey. A total of 94.6% of them declared knowledge of the term MRONJ. However, the length of bisphosphonates persistence in the body was known to 51.5% of participants, while the knowledge of oral and maxillofacial surgeons concerning this topic was significantly higher (87.0%). Conclusion: Dental and maxillofacial surgeons presented the highest level of knowledge about MRONJ. The remaining groups did not differ in their knowledge. It must be noted that the knowledge of the students was similar to that of dentists. A better level of knowledge by dentists could contribute to a decline of the occurrence of the disease in future. Theoretical and practical initiatives should be promoted to improve the knowledge about MRONJ.
This observational cross-sectional study evaluated the differences in condylar guidance angles during mandibular protrusion and mouth opening using digital axiography and CBCT. A total of 30 healthy subjects (60 TMJs) aged 20–24 years were examined. Mandibular movements were recorded using the Modjaw system, and fossa height was assessed from CBCT images. A statistically significant correlation was observed between condylar angles measured during protrusion and opening (r = 0.57, p < 0.001). Protrusive measurements were more consistent, while opening exhibited greater variability. The results suggest that protrusive movements are more reliable for articulator programming. Digital tools such as Modjaw can enhance precision and workflow efficiency in TMJ diagnostics.
