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.
