제안 방법
- A treatment plan was developed after collecting the patient’s needs; his first priority was fixed restorations with minimum number of surgeries.
- Removal of hopeless teeth and implants, strategic use of remaining implants for the new restoration, remodeling of occlusion, and prevention of attrition due to strong bite force. As the patient wanted new implant prostheses instead of conventional dentures, implant installation after removing the diseased implants were planned. To minimize the risk of recurrent peri-implantitis, attention in designing restorations that are favorable to periodontal tissues was necessary.
- Bite registration with wax-rim made from baseplate wax (TruWax, Dentsply Sirona, York, PA, USA) and PVS material (Futar-D, Kettenbach GmbH&Co, Eschenburg, Germany) reflecting the removable provisional restoration was taken.
- A set of removable prosthesis was then delivered and implant installation was scheduled after 3 months. Cone beam computed tomography (CBCT) was taken with a radiographic stent, followed by planning of the location and size of implants to be installed.
- Final impressions were taken with conventional methods with splinted pick-up copings (Osstem, Seoul, S. Korea), individual trays (SR Ivolen, Ivoclar Vivadent AG, Liechtenstein), border molding with compound material (Peri Compound, GC Corporation, Tokyo, Japan), and PVS (ImprintII Garant) (Fig. 5A, 5B).
- From the observations, four main key points for the treatment were considered. Removal of hopeless teeth and implants, strategic use of remaining implants for the new restoration, remodeling of occlusion, and prevention of attrition due to strong bite force. As the patient wanted new implant prostheses instead of conventional dentures, implant installation after removing the diseased implants were planned.
- They were additionally adjusted on the actual articulator. Upon trying them in the patient, bite registration (Aluwax, Aluwax Dental Products, Allendale, MI, USA) and clinical remounting was performed. After adjustment, zirconia crowns were cemented with the same dual-cured resin cement and zirconia bridges were cemented to custom abutments with zinc oxide/eugenol cement (Temp-Bond, Kerr, Orange, CA, USA) (Fig.
대상 데이터
- After checking the amount of keratinized mucosa on the mandible, a total of 6 internal conical hex implants (TSIII SA, Osstem, Seoul, Korea) were installed. 5.0 mm diameter implants on both molars, 4.5 mm diameter implants on both premolars, and 3.0 mm diameter implants on both lateral incisors were selected. Guided bone regeneration (GBR) on the left mandible with the same materials as ARP was additionally performed to provide extra bone volume.
- A 69-year old male patient visited the Department of Prosthodontics, Ewha Womans University Mokdong Hospital with a chief complaint of bleeding gums and mobility of teeth (Fig. 1, Fig. 2). He had medical history of hyperlipidemia and Alzheimer’s disease and was taking medication accordingly.
