Removal of infected teeth, dental implant surgery, fabrication of metal-ceramic crowns, screw-retained metal-ceramic crowns borne by implants
Treatment phase II – dental implant surgery
Male patient aged 55
- Professional tartar removal and teeth polishing was performed due to a massive pile-up of sub and supragingival tartar.
- At the previous session 6 decayed and infected lower molars and their periodontal pockets were eliminated.
- The patient was handed over an immediate denture for the 3 months of healing.
Second treatment following 3 months of healing: 3 workdays, the installation of implants
Following 3 months’ healing the bone was ready for the installation of implants. For a thorough planning of the site and size of the implants a CBCT (Cone beam computed tomography) scan was recorded to examine the bone mass in 3 dimensions prior to the intervention.
The height and width of the bone were ideal for the installation of implants. By securing 3 implants in each quadrant a stable bridge can be achieved. Since the stability of the implant exceeded 30 Ncm on installation the implant was covered with a healing abutment aka. gingiva former allowing the gums to heal into the perfect shape for the permanent abutment in the process of osseointegration. In the lower jaw bone a crucial nerve passes highlighted in pink in the CT scan. The dentist must accurately pinpoint the path of the so-called inferior alveolar nerve to prevent drilling into the nerve when drilling the bone which may cause permanent lip paralysis.
Following implantation, the provisional denture is relined with a soft material (soft reline). In the course of healing, remember to not only clean your natural teeth and provisional dentures thoroughly, but also the gingiva formers with a tooth brush.
The treatment can be resumed after 3 months’ healing with the fabrication of permanent replacements, viz. metal-ceramic bridges borne by natural teeth and lower implants. There is a time window of 3 months for selecting the type of implant crowns during which the patient can decide whether they favour a screw-retained implant crown or cement-retained one.
