Zusammenfassung:Occlusal analysis is a substantial tool for the functional improvement evaluation after using implant‐retained overdenture comparing to complete denture without dental implant retaining. To evaluate occlusal pattern, chewing force distribution in mini‐dental implant‐retained mandibular overdentures by computerised occlusal analysis system and to compare patient satisfaction after 1‐year function. Thirty‐one patients wearing complete dentures were included in the study. Prior to mini‐dental implant‐retained treatment, all patients were assessed for occlusion and force distribution using computerised occlusal analysis system (T‐Scan®), and then, all patients received two mini‐dental implant‐retained mandibular overdentures. Mini‐dental implants were immediately loaded using low vertical profile attachments (Equator®). T‐Scan® was used to evaluate chewing force and force distribution at 1 day, 3 months, 6 months and 12 months. The patient satisfactions before implant placement and after 1 year were evaluated using questionnaires which included satisfaction of denture quality, psychosocial behaviour and chewing efficiency modified from the validated questionnaires. Clinical evaluation of two mini‐dental implant‐retained mandibular overdentures showed 100% success rate after 1 year. T‐Scan® demonstrated that maximum occlusal contact force increased continuously. The force distribution; the tooth contact number increased over the period. At 1‐year follow‐up, overall patient satisfaction was significantly greater than before receiving mini‐dental implant treatment (P
