Abstract:
Background:Implant restoration necessitates meticulous attention to the profile, and texture of gingival soft tissue. The
healing abutment plays a critical role as a gingival shaping tool, with its neck design significantly impacting soft tissue
profile and crown aesthetics.
Aim:This study explores the impact of a modified anatomic healing abutment (MAHA) on morphological changes in
gingival soft tissue and patient satisfaction following mandibular first molar implant restoration.
Materials and Methods:Thirty patients with a single missing mandibular first molar undergoing implant repair were
randomly assigned to either the control group (n=15) or the experimental group (n=15). The experimental group received
a MAHA post-dental implantation, while the control group received a standard healing abutment. Both groups underwent
crown restoration after 2 months. Peri-implant soft tissue index, Pink Esthetic Score (PES), and patient satisfaction were
assessed at postoperative day (T0), 1 month (T1), 3 months (T2), and 6 months (T3). Independent sample t-tests were
conducted with a significance level of α=0.05, where P < 0.05 indicated statistical significance
Results:No significant differences in peri-implant soft tissue index were observed between the experimental and control
groups at T0, T1, T2, and T3 (P>0.05). The mean PES value in the experimental group exceeded that of the control group
at T0, T1, and T2 (P < 0.05). VAS scores showed no significant differences between the groups at T0, T1, and T3 (P>0.05),
but at T2, the experimental group exhibited higher satisfaction levels than the control group (P < 0.05)
Conclusion:The modified anatomic healing abutment for a mandibular first molar implant demonstrates superior soft
tissue contouring compared to the standard healing abutment, leading to heightened patient satisfaction during prosthesis
wear. Clinical Significance: The use of a MAHA in mandibular first molar implant restorations can enhance soft tissue
contour and improve early esthetic outcomes without compromising peri-implant health. This approach also contributes
to increased patient satisfaction during the prosthetic phase, supporting its clinical application for optimizing both functional and esthetic results in implant dentistry.
