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.

“…Female parts were fabricated from dissimilar materials. Titach matrix was composed of a titanium cap surrounded by a silicone sleeve, while locator R-Tx matrix was formed of titanium housing with various nylon inserts confined in it of different retention; zero retention insert (gray), low retention insert (blue), medium retention insert (pink) and high retention insert (clear) [ 20 , 25 ].…”

“…The same mandibular mold was used for pouring a mandibular model made of epoxy resin (Ramses Medical Products Factory, Alexandria, Egypt) with a 7.5 mm width at the canine region. The epoxy resin was covered with mucosa simulating material made of flexible polyurethane of 1.5 mm thickness [ 25 ]. Maxillary and mandibular trial denture bases made of autopolymerizing acrylic resin (Special Tray Material; Acrostone Co Ltd, Cairo, Egypt) with wax occlusion rims were constructed on the stone models and mounted on a mean value articulator, on which maxillary and mandibular acrylic teeth (Acrostone Plus Double Layer anterior and posterior teeth; Acrostone Co Ltd, Cairo, Egypt) were arranged and adjusted.…”

“…A vertical cyclic tension–compression test was conducted utilizing a custom-made cyclic loading machine simulating overdenture insertion and removal [ 25 ]. Every overdenture was subjected to 1000 cycles, corresponding to 1-year clinical use with an average of 3 cycles each day [ 28 , 29 ].…”

“…A T-shaped acrylic resin plate was fabricated to be attached to the occlusal surfaces of the acrylic resin teeth at the incisal and first molar regions of overdentures by using autopolymerizing resin. The center of the T-shaped plate was attached to the upper member of the cyclic loading machine to perform removal and insertion cycles of the overdentures [ 25 ] (Fig. 2 ).…”

Background Attachment material is one of the contributing factors to the degree of wear of the attachment components in mandibular implant-retained overdentures. The purpose of this in vitro study was to compare the wear behavior of 2 different attachment systems of dissimilar materials in mandibular implant-retained overdentures by qualitative and quantitative methods. Methods Two attachment systems of different materials were utilized (n = 16); Titach (Dental Evolutions Inc, Beverly Hills, CA, USA) with a titanium-to-titanium interface and Locator R-Tx (Zest Anchors Inc, Escondido, CA, USA) with a titanium-to-nylon interface. One thousand cycles of overdenture insertion and removal simulating 1-year clinical use were performed. All matrices were removed from the overdentures and all patrices were unscrewed from the implants for wear assessment quantitively using a stereomicroscope and qualitatively using a scanning electron microscope. Data were analyzed by using an independent sample t test. Results After cyclic loading, stereomicroscopic findings showed that the Titach group had statistically significant higher wear value than the Locator R-Tx group (p < 0.001). Moreover, scanning electron microscopy images showed noticeable abrasion in Titach patrix at the area of highest convexity. However, the Locator R-Tx matrix displayed an apparent tear of rubber inserts. Conclusions Titach attachment with the titanium-to-titanium interface revealed more wear than Locator R-Tx attachment with the titanium-to-nylon interface. Thus, the type of attachment material influences the degree of wear of the attachment components.
