Abstract: Objective : The aim of the present study is to investigate the maximum voluntary molar bite force in individuals with Angle's Class I and Angle's Class II malocclusions with different facial morphologies. Materials and Methods : The study involved 300 individuals from Anil Neerukonda Institute of Dental Sciences in Sangivalasa, aged 18 to 35 years. Inclusion criteria specified participants with Angle's Class I or Class II malocclusion, a full complement of teeth (excluding third molars), and no history of orthodontic treatment, crossbites, extractions, significant restorations in first molars, traumatic occlusion, or missing first molars. Using selected lateral cephalometric measurements and clinical assessments, participants were divided into two groups: 150 with Angle's Class I malocclusion (Group I) and 150 with Angle's Class II malocclusion (Group II). Each group was further categorized into three subgroups—Normodivergent, Hypodivergent, and Hyperdivergent—based on Basal Plane Angle and Jarabak's Ratio, with 50 subjects in each subgroup (Subgroups: IA, IB, IC, IIA, IIB, IIC). A Gnathodynamometer with a digital pressure gauge and metal biting fork was used to measure molar bite force. Data analysis was performed using SPSS v.22. Paired t-tests compared measurements, and one-way ANOVA evaluated mean differences among groups (P <0> Angle's Class II Hypodivergent > Angle's Class I Normodivergent > Angle's Class II Normodivergent > Angle's Class I Hyperdivergent > Angle's Class II Hyperdivergent. Conclusion : Maximum bite force is greatest in Hypodivergent individuals, followed by Normodivergent, and is lowest in Hyperdivergent individuals. Additionally, people with Angle’s Class I malocclusion have a higher bite force compared to those with Angle’s Class II malocclusion. The order of maximum bite force is as follows: Angle’s Class I Hypodivergent Angle’s Class II Hypodivergent Angle’s Class I Normodivergent Angle’s Class II Normodivergent Angle’s Class I Hyperdivergent Angle’s Class II Hyperdivergent.
