Abstract: PURPOSE: To assess the predictability of using the roots of the maxillary anterior teeth in advantageous positions to guide immediate implantation and enhance the positioning precision of placed implants. METHODS: Existing root canals were used in the test group for manual preparation of the implant bed, whereas traditional freehand techniques were employed in the control group. The three-dimensional position of the placed implants was measured using radiological images taken on the day of surgery and again six months post-surgery and evaluated using self-developed rating criteria for the radiographic positions of the implants. The spatial relationship between the axial orientation of the implant and prosthetic crown was assessed using a self-developed scoring scale. Statistical analysis of the three-dimensional positional imaging scores of the implants was conducted immediately after surgery and at six months post-implantation. Intergroup statistical analysis was conducted on the scores reflecting the spatial relationship between the axial orientation of the implants and their prostheses. RESULTS: The test group demonstrated significantly higher scores for the labial-palate and horizontal positions, both immediately following surgery and at six months post-implantation, than the control group. Furthermore, the test group significantly outperformed the control group in terms of scores reflecting spatial relationships. CONCLUSIONS: Utilizing the roots of the anterior teeth in advantageous positions as guides for preparing implant beds can lead to more ideal implant placement than traditional manual techniques.
