case_images: Their residual alveolar ridges in the mandible were excessively resorbed and atrophied (Figure 1); mental foramina were just below the mucosa overlying alveolar ridges.
case_images: A CBCT scan of one patient with extensively resorbed mandibular alveolar ridge.

case_images: Panoramic radiographs and CBCT scans (Figure 2) revealed that the height of the mandible between the mental foramina was less than 10 mm with a reduced buccolingual width.
case_images: (a) Extensively resorbed denture-bearing area in the mandible; (b) four mini dental implants inserted; (c) mandibular overdenture reinforced with the CoCr framework with matrices and O-rings inserted.

case_images: Each patient received four MDIs (Ti-6Al-4V, Dentium, Seoul, Korea; 2.0 or 2.5 mm wide, 6 or 8 mm long) in the interforaminal region without reflecting a flap (Figure 3(b)). All new mandibular overdentures were reinforced with the CoCr framework to prevent denture fractures (Figure 3(c)).
case_images: Panoramic radiographs (a) before treatment, (b) after one year, and (c) after 2 years of wearing the mandibular overdenture.

case_images: During insertion one mini dental implant fractured due to an insertion torque > 45 N/cm and was left as a sleeping implant in the bone, while an additional MDI was inserted for proper denture retention (Figure 4(a)). The control panoramic radiographs were made at the 1-year and 2-year observation stages (Figure 4).
case_images: Mean summary scores of the OHIP-14, chewing function questionnaire (CFQ), and orofacial esthetic scale (OES) prior to the treatment, after receiving new dentures and finished adjustments, at the one-year follow-up examination and the 2-year follow-up clinical examination.
