  • The therapeutic goal of implant dentistry is not merely tooth replacement but total oral rehabilitation. Considering dental implants as a treatment option can be provided patients with positive, long-term results. Implant dentistry has gone through many phases over the years. Modern technology and design allows us to predictably place our dental implants often load the implants at the time of placement. The purpose of this study is to evaluate the implant stability after immediate loading in dogs. The control group was performed delay loading and experimental group was immediate loading. Each group was measured periotest value(PTV) to evaluate clinical mobility and performed radiographic examination to evaluate marginal bone loss. Statistically significant difference was not founded in control group between experimental group in PTV(P>0.05) and marginal bone loss(P>0.05). Finally, implant stability after immediate loading was similar to delay loading implant.

  • During the past several years, significant advances have occurred in the utilization of osseointegrated implants for the treatment of partially edentulous patients. One of the biggest purposes for treating of these patients is the high demand for improved esthetics, especially in the anterior region. For this esthetics, the new trend in dental implants is the immediate placement and immediate superstructure fabrication. The refined surgical technique, the skillful soft tissue management, and the proper prosthetic coordination are the main factors to achieve natural looking of implant supported prosthesis. The customized provisional restoration and the customized impression coping are recommended for the optimal peri-implant soft tissue contour. The basic concept of Frialit 2 system was the immediate replacement of a tooth with root-analog fixture after extraction. This system guarantees an ideal result in function and esthetics. The ceramic abutment system offers improved quality in the respect of esthetics, fitness, translucency, and biocompatibility. In this clinical report, the final restoration made with IPS Empress 2 crown on the CeraBase abutmen of Frialit 2 system allowed the reproduction of the natural vitality of tooth and adjacent gingiva.

  • Recently many studies have been published on application of immediate loaded implants. However, the immediate loading protocol has not been well documented. The purpose of the present study was to evaluate the stress distribution between bone-implant interfaces and the effect of implant length in the anterior maxilla using 3 dimensional finite element analyses. The diameter 4.0 mm threaded type implants with different length(8.5 mm, 10.0 mm, 11.5 mm, 13.0 mm, 15.0 mm) were used in this study. The bone quality of anterior maxillary bone block was assumed to D3 bone. Bone-implant interfaces of immediately loaded implant were constructed using a contact element for simulating the non osseointegration status. For simplification of all the processing procedures, all of the material assumed to be homogenous, isotropic, and linearly elastic. The 178 N of static force was applied on the middle of the palatoincisal line angle of the abutment with $120^{\circ}$ angle to the long axis of abutment. Maximum von Mises stress were concentrated on the labial cortical bone of the implant neck area, especially at the cortical-cancellous bone interfaces. Compared the different length, highest peak stress value was observed at the 8.5 mm implants and the results indicated a tendency towards favorable stress distribution on the bone, when the length was increased. Presence of cortical bone was very important to immediate loading, and it appears that implants of a length more than 13 mm are preferable for immediate loading at the anterior maxilla.

  • Thin labial plate will be resorbed after extraction. Immediate implantation cannot prevent soft and hard tissue loss. Bone graft can be necessary in the immediate implantation after anterior tooth extraction. Slowly-resorbed or non-resorbable bone graft material have many advantages in esthetic area because of maintenance of volume. The clinicians should select the adequate cases of immediate implantation according to the indication and contraindication.

  • In the recent studies, many authors have reported that the success rate of immediate implantation has no difference compared to conventional staged implantation. Although the immediate implantation has many advantages over conventional approach, many clinicians don't seem to practice because they think that most of the extraction sockets will have some bony gab with defects around implant and that this situation makes the result of immediate implantation unpredictable. We clinically analyzed 23 implanted sites of 18 patients treated with immediate implantation in our hospital from September 2003 to January 2004. The $ITI^{(R)}$. dental implant system was used and GBR procedure with $Bio-Oss^{(R)}$. and $Bio-Gide^{(R)}$. was done simultaneously. The pre & post-op. measurements were recorded such as alveolar crest-adjacent tooth CEJ distance, gingival crest-adjacent tooth CEJ distance, existence of periapical lesion, vertical defect around the extraction socket, horizontal defect around the extraction socket, probing depth, radiologic change of alveolar crest height. We report a positive outcome about immediate implantation with review of literatures.

  • Since $Br^{\circ}anemark$ introduced the osseointegrated implants, they have been granted for useful methods for the restoration of oral function. The original $Br^{\circ}anemark$ protocol recommended long stress-free healing periods to achieve the osseointegration of dental implants. However, many clinical and experimental studies have shown that the osseointegration is no wonder in almost cases and that early and immediate loading may lead to predictable osseointegration. So we are willing to introduce the Satellite Abutment newly invented for immediate loading. We think that it will make the occlusal forces dispersed to surrounding bone and that we can restore the oral function immediately after implant installation not disturbing osseointegration. In case of using Satellite abutment, stress concentrated to bone contact area of implant was distributed not only fixation plate and screws but also superior, middle portion of implant and cortical layer of jaw bone. It was clearly decreased on the bone contact surfaces around dental implants. 1. Stress was decreased more than 76.5% when satellite straight abutment was used. 2. Stress was decreased more than 50% when satellite angled abutment was used. 3. The stress around dental implant was well distributed along the cortical bone surface and the fixation plate and screw. This study concludes that satellite abutment can be used as all immediate loading implant prothesis because it was possible to distribute periimplant occlusal stress through implant contact bone surface and cortical layer of jaw bone.

  • Developing of digital technique, it is possible to fabricate implant prostheses for edentulous area using intraoral 3-dimentional information throughout implant diagnosis and treatment process. It is being changed that from the method using CAD/CAM, producing prostheses by model scanning after conventional impression and model processing, to the method of fabricating implant provisional restorations and customized abutments by digital impression after connecting digital impression copings (scanbody) and implant fixtures without models. But, this digital method has not been actively used for implant prostheses not yet. Specially, it is short of intraoral digital impression cases for immediate provisional restorations of the maxillary anterior implants. The gingival contour impression of maxillary anterior area is very important for esthetic restorations. Accordingly, in this case report, the using a digital impression coping (scanbody) and digital impression by CEREC Omnicam (Sirona, Bensheim, Germany) or Trios (3shape, Copenhagen, Denmark) were introduced for immediate provisional restorations in 3 cases needed a single implant restoration in maxillary anterior area. The clinical results were satisfactory on the convenience and accuracy of digital impression technique and the good esthetics of final restorations.

  • The development of cone beam computerized tomography (CBCT) allows three-dimensional analysis of the patient's anatomy. The surgical guide is a combination of CBCT, computer-aided design/computer-aided manufacturing (CAD/CAM) and implant diagnostics software, which allows well planned prostheses design and ideal implant placement. Guided surgery minimizes possible anatomical damage and allows for more reproducible treatment planning. In this case, the operation time was shortened by using a surgical guide for multiple implants placement in a fully edentulous patient. Immediate loading were performed more easily using preliminary preparation of provisional prosthesis. The patient was satisfied with improved esthetics and chewing function.

  • Despite the greater retention and low maintenance of bar attachment system, the longer clinical time and increased number of visits were the assignments to overcome in bar attachment system. This case report describes SFI-Bar$^{(R)}$ (Cendres et Me$\'{e}$taux, Biel/Bienne, Switzerland) to be solve those problems. A 65-year-old female, who had severely absorbed mandible, hoped to wear a stable mandibular denture without pain. As soon as two implants were placed on mandible, a tube bar was connected to two adaptors connected to each implant. The length of the tube bar was adjusted considering inter implant distance, and reconnected to the adaptors. Finally a female part was seated beneath the denture. This case report showed that a satisfactory clinical result was achieved by delivering bar overdenture immediately after implant placement without laboratory procedure.
