Enhancing implant accuracy by guiding immediate placement with favorably aligned anterior maxillary roots

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.

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.

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.

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.
