Impact of TITACH Attachment on the Retention for Mandibular Implant Overdentures

Aims: This clinical study aimed to evaluate the impact of TITACH attachment on the retention for mandibular implant overdenture . Subjects and Methods: Eight edentate’s patients were eligible for this current work. All participants were received complete maxillary and mandibular dentures. Two dental implants were surgically inserted bilaterally in mandibular canine region. After 3 months of Osseo-integration, dental implants were exposed, healing abutments were screwed. According to techniques of TITACH incorporation to overdenture, patients were divided into two equal groups, Group I: 4 patients received mandibular implant overdenture that retained by direct incorporation of TITACH attachment. Group II: 4 patients received mandibular implant overdenture that retained by TITACH attachment with indirect incorporation technique. Retention was evaluated by digital force-meter. This evaluation was performed after 1 week of overdenture delivery (T0) and 6 months after overdenture delivery (6). The average retention was analyzed. The two groups were compared with independent t-test while paired groups were compared by paired t-test Results: Retentive forces of both incorporation techniques of TITACH attachment at different evaluation times revealed that, statistically significant difference in retentive forces at different evaluation times. On the other hand, there was statistically insignificant difference when group I and II were compared at different evaluation times. Conclusion: The TITACH attachment group showed favorable retentive force with 2 different incorporation techniques. The TITACH attachment could be a suitable choice when increased retention is required. However, the TITACH attachment showed high percentage change in retentive force but still accepted in both direct and indirect techniques.
