“…[ 1 4 ] Also, it was reported that wearing a single implant mandibular overdenture (SIMOD) improves oral health and OHRQoL. [ 5 6 7 ] A SIMOD is a conservative and cost-effective treatment for edentulous patients who are not comfortable with unstable CDs. [ 8 ] Moreover, a SIMOD is comparable to a standard 2-implant retained overdenture.…”

Aim: To study the masticatory efficacy and oral health-related quality of life (OHRQoL) of participants wearing a mandibular overdenture retained by an immediate loading single implant with different occlusal tooth forms. Materials and Methods: For this nonrandomized controlled trial study, 27 edentulous participants were selected and randomly divided into three groups (n = 9) based on occlusal tooth forms of the mandibular implant overdenture (MIOD). Group I: participants received an MIOD with an anatomical tooth form; Group II: participants received an MIOD with a semianatomical tooth form; and Group III: participants received an MIOD with a nonanatomical tooth form. For each participant, a single implant (screw root form) was inserted into the midline of the mandibular ridge to support the MIOD. For each group, the masticatory efficiency was evaluated after 3 months, and the OHRQoL of the participants was evaluated after 3 and 6 months. One-way ANOVA and post hoc Tukey’s test were used for data analysis (P < 0.05). Results: The masticatory efficiency of the anatomic and semianatomic tooth forms was higher than that of the nonanatomic (P < 0.05). Moreover, the improvement in the participants’ OHRQoL in the anatomic group was more significant than that of other groups (P < 0.05). Conclusion: There was a greater improvement in masticatory efficiency and participants’ OHRQoL when fitted with an anatomic tooth form mandibular overdenture retained by an immediate loading single implant than with a semianatomic or nonanatomic tooth form.
