A 30 year old female patient presented with symptomatic irreversible pulpitis of both  LR6 and LL6 teeth. Cone beam computed tomography (CBCT) of the region revealed, a middle mesial canal in tooth LR6, and a middle distal canal in tooth LL6. The case was managed with K files (Dentsply Maillefer), K file Nitiflex (Dentsply Maillefer), Protaper Next (Dentsply Maillefer), XP-endo Shaper (FKG) and BT-Race (FKG) under copious irrigation with sodium hypochlorite, ethylenediaminetetraacetic acid and saline. Premixed bioceramic sealer TotalFill (FKG) and gutta percha were used for root canal obturation. The access cavities were restored using glass ionomer cement and resin composite. A 12-month review showed that the teeth were functional within normal periodontal parameters. The favourable clinical and radiographic outcome in this case demonstrated that the treatment approach followed is effective in solving complex clinical challenges.

Introduction. The use of basal implantation permitted to perform prosthetic rehabilitation of patients with defects of the upper jaw, where traditional dental implantation could not be used. Materials and methods. We present the clinical case of a patient with a subtotal defect of the right half of the  maxilla after removal of a benign tumor, for prosthetic rehabilitation through basal dental implantation.Results and discussion. According to the significant post-resection deficit of the bone, it was decided to create a fixed prosthetic construction with support on 3 dental implants located in “strategic” areas – floor of the nose, tubero-pterygoid area and zygomatic body. The treatment was uneventful. No complications were detected during 9 years of follow-up observation.

Conclusions. This clinical case successfully demonstrates the possibility of rehabilitation of patients with post-resection defects of the upper jaw trough basal dental implants with fixed prosthetic bridge-like constructions.
