The occlusion design of dental implants is related to the growing popularity of dental implantology. This paper discusses the occlusion design of the edentulous implant prosthesis and the relationships between stress change and the alveolar bone and between the occlusal design and implantation complications. The horizontal relationship of condyle, the design of the canine-guided occlusion, and the similarities and differences between the dental implant and the natural teeth on biteforce response are mentioned.

Nowadays, dental implant is one of the widely used treatment options for edentulous patients. Recently, a method of improving the accuracy of implant surgery using an implant surgical guide has been introduced and widely used in order to accurately place the implant in a proper position. Full-guided and half-guided implant surgery can be distinguished according to the level of surgical guide application during the implant surgery. It is true that full-guided implant surgery exhibits higher accuracy, but half-guided implant surgery is often performed in a clinical situation due to the factors such as the circumstances of the operation. A partially edentulous patient who lost teeth due to tooth fracture and periodontal disease was treated using implant and fixed prosthesis. Half-guided implant surgery was performed using an implant surgical guide during implant surgery, the accuracy of implant placement was analyzed.

OBJECTIVETo investigate the clinical feasibility and technical characteristics of immediate loading and to access the short-term clinical results of treatment.

METHODSThis study included 3 completely edentulous patients and 24 patients who were partially edentulous from March 1999 to December 2003. 21 implants were immediately loaded and provided support for mandibular overdenture for 3 fully edentulous patients. 30 implants were placed in 21 partially edentulous patients and implants were immediate loaded in edentulous mandibular providing support for fixed provisional prosthesis within 6 months. Then, metal-ceramic crowns were completed. All patients were followed up by 1, 3, 6, 12 months and the patients were checked every 12 months.

RESULTSA total of 42 implants were loaded immediately. From March 1999 to December 2003, no implants were lost during follow-up (range 3 to 49 months, mean of 28 months). No infections, nerve or sinus damage or other sequelae occurred. No implants exhibited peri-implant radiolucencies. Moreover, immediate loading seems to increase the ossification of the alveolar bone around endosseous implants. Patients were satisfied with the treatment.

CONCLUSIONSThe data and the experience described in this study indicate that immediate loading with restorations using appropriate surgical and restorative techniques can predicate the completely edentulous and partially edentulous mandible in some cases. Further study is needed to determine the long-term result of immediately loaded implants.

OBJECTIVETo evaluate the outcomes of attachments prosthesis in patients with complicated intraoral situation.

METHODSThirty-eight patients provided with fixed-removable partial denture were followed up for 1 to 5 years. A total of 51 attachments restoration supported by 139 abutments were included.

RESULTSGood retention and stability of the restoration were achieved; masticatory function and esthetic effects were recovered satisfactorily.

CONCLUSIONSFixed-removable partial denture is an effective method for patients with complicated intraoral situation.

OBJECTIVETo assess the effect of removable partial dentures (PRD) restoration on oral health-related quality of life (OHRQOL) of subjects with shortened dental arches (SDA) using the Chinese version of the Oral Health Impact Profile (OHIP-14).

METHODSConsecutive patients with shortened dental arches were recruited from the Department of Prosthodontics, Foshan Chancheng Hospital of Stomatology. The Chinese version of OHIP-14 was administered to each subject before treatment and after treatment. The subjective outcomes of removable partial dentures therapy on SDA were collected and the pre- and post-treatment scores of the Chinese version of OHIP-14 were compared.

RESULTSAfter treatment, significant decrease in patients' total score of OHRQOL [before: 9 (6, 12) ; after: 4 (2.25, 6)] was detected, as well as physical pain subscale, physical disability subscale and handicap subscale; and the score of OHRQOL in function limitation subscale increased [before: 0(0,0); after: 2(1, 2)].

CONCLUSIONSThe main impacts of shortened dental arch with intact anterior region affecting patients' OHRQOL are physical disability.From a quality-of-life perspective, patients with SDA can perceive benefits from RPD.

OBJECTIVETo evaluate the application and the effect of edentulous ridge expansion(ERE) technique in maxillary endossenous implant placement.

METHODS49 patients with maxillary alveolar ridge atrophy received edentulous ridge expansion using condenser. In order to be similar to natural root, dental implants were selected and placed to tooth missed sites according to the requirements of aesthetics, function and dimension.

RESULTS49 patients with atrophied alveolar ridge received 86 implants. The labio-lingual width augmented from 3.3 to 5.4 mm and the alveolar ridge height from 2 to 7 mm 6 months after operation. The implants osseintergrated tightly with alveolar bone and second-step prosthesis was performed 6 months after implant placement.

CONCLUSIONThe edentulous ridge expansion technique can meet the requirements of aesthetics and function and is applicable to endossenous implant placement in maxilla. The method is simple and valuable to clinical application.
