部分牙缺失的即刻修复

为保证种植体初期稳定性,形成良好的骨整合,通常认为需在种植体植入后3-6月再延期修复。然而近年来,越来越多文献报道了牙列缺损即刻修复的病例,且取得良好的临床效果。但是,对牙列缺损的即刻修复尚存一些争议。本研究回顾近年文献同时结合本课题组的研究结果对牙列缺损即刻修复进行评估,并提出相关研究进展。     

Zygoma implant-supported prosthetic rehabilitation after partial maxillectomy using surgical navigation: a clinical report

The rehabilitation of patients with acquired defects of the maxilla is a challenge in terms of reestablishing oronasal separation. In most patients these goals are met by means of prosthetic rehabilitation with an obturator prosthesis. If the remaining dentition does not offer sufficient retention and support, the placement of zygoma implants can enhance the stability of the prosthesis. Due to the anatomic intricacies of the zygomatic bone and the implant length, computer-supported navigated implant placement can be advantageous. In the following clinical report, a diabetic patient with a status of posthemimaxillectomy secondary to aspergillusis infection is presented, in whom a zygoma implant was placed using a CT scan-based navigation system. A special retentive anchoring abutment was used to integrate the zygoma implant into a telescopic crown-retained denture on the residual dentition. This tooth-implant-supported obturator prosthesis restored function and phonetics, as well as esthetics, for this young patient.

Prosthodontic Rehabilitation with a Telescopic Prosthesis of a Nonsyndromic Oligodontia Patient

Oligodontia is the congenital absence of six or more permanent teeth, excluding the third molars. Oligodontia of permanent dentition is a rare occurrence. Preservation of the remaining deciduous dentition in such situations is important for both functional and esthetic rehabilitation of the patient. This clinical report describes the rehabilitation of a 16‐year‐old male with oligodontia of permanent teeth treated by an interdisciplinary team of prosthodontist, pedodontist, and orthodontist. The remaining deciduous dentition was endodontically treated. Occlusal vertical dimension (OVD) of the deciduous dentition was assessed. A full‐mouth single piece porcelain‐fused‐to‐metal telescopic prosthesis for the maxillary and mandibular arches was planned with a minimal increase in OVD. The telescopic prosthesis provided excellent retention, stability, esthetics, and stress equalization on the remaining deciduous dentition. Maintenance of oral hygiene procedures was simplified for the adolescent with the telescopic prosthesis. Preservation of remaining deciduous dentition and fabrication of a telescopic prosthesis in this patient provided an effective esthetic and functional rehabilitation.

Prosthodontic rehabilitation of non-syndromic oligodontia case with telescopic prosthesis

Oligodontia is the congenital absence of six or more permanent teeth excluding the third molars. Oligodontia of permanent dentition is a rare occurrence. Preservation of the remaining deciduous dentition in such situations is important for both functional and esthetic rehabilitation of the patient. This case report describes the rehabilitation of a 16 year old male with oligodontia of permanent teeth treated by an interdisciplinary team of Prosthodontist, paedodontist and orthodontist. Endodontic treatment of all the remaining deciduous dentition was done. Vertical dimension of deciduous dentition occlusion was assessed. Full mouth single piece porcelain fused to metal telescopic prosthesis for maxillary and mandibular arch was planned with minimal increase in vertical dimension of occlusion. Telescopic prosthesis provided excellent retention, stability, esthetics and stress equalization on the remaining deciduous dentition. Maintenance of oral hygiene procedures was simplified for the adolescent with the telescopic prosthesis. Preservation of remaining deciduous dentition and fabrication of a telescopic prosthesis in this patient provided an effective aesthetic and functional rehabilitation for the patient.     

Clinical report on defective dentition

The "8020" objective seems difficult to achieve, but at least 20 teeth are needed based on difficult cases of defective dentition. Our clinical experience shows that at least 18 teeth are needed to keep 4 occlusal supports. If the number of occlusal supports falls below 4, defective dentition may easily deteriorate to more clinically difficult cases. From our long-term experience, patients over 80 years old who still have 20 teeth usually have stabilized occlusal supports, while many cases who have partially lost their occlusal support do not achieve the 8020 goal. Prevention of partial defects of teeth for restoration of caries and active prosthesis for defects are important to achieve the 8020 goal. Furthermore, continuous follow-up and preventive support are important. If continuous clinical correspondence is possible, 8020 may be achievable in about 80% of all cases.     

Use of linear occlusion with fixed restorations opposing a mandibular complete denture: a clinical report

Restoring an edentulous mandibular arch opposing maxillary natural dentition with conventional occlusal schemes historically has proven to be extremely difficult. Using a noninterceptive anterior and posterior occlusal concept with a myostatic peripheral border extent provides a means to enhance stability of the mandibular prosthesis.

The effect of dental profile on daily functions of the elderly

The aim of the study was to evaluate statistically dentition and its effect on daily functions for a group of elderly volunteers. The study was conducted on 144 elderly people (86 males, 58 females) living in different nursing homes in Ankara, Turkey. Their ages varied between 60 and 100 years. Data assessed as dentition variables were number of teeth remaining and prosthesis use. Nearly 55% of the residents were edentulous and removable prosthesis users. The mean number of remaining teeth in subjects aged 60–69 was highest for all age groups in both sexes. The level of education and dental insurance of these subjects were also correlated with the dentition of elderly subjects. We found a statistically significant increase in the number of removable prosthesis users among educated and insured subjects. Functional capacity was better when the subjects had more remaining teeth or a removable prostheses. It is revealed by this study that healthy and good dentition prevents the decline of daily function and improves the social interaction and general well being of the elderly.
