Purpose: To compare virtual planning accuracy of novel computer-assisted, template-based implant placement techniques, which make use of CAD/CAM stereolithographic surgical templates with or without metallic sleeves. Furthermore, to compare open versus closed sleeves for templates without metallic sleeves. Materials and methods: Any partially edentulous patients requiring at least one implant to be placed according to a computer-assisted template-based protocol were enrolled. Patients were randomized according to a parallel group design into two arms: Surgical template with or without metallic sleeves. Three deviation parameters (angular, horizontal, vertical) were defined to evaluate the discrepancy between the planned and placed implant positions. Results: No implants failed, and no complications were experienced. Forty-one implants were placed using surgical templates with metallic sleeves while 49 implants were placed with a surgical template without metallic sleeves. Of these, 16 implants were placed through open sleeves and 33 through closed sleeves. There was a statistically significant difference in angle (p = 0.0212) and in the vertical plan (p = 0.0073) with lower values for implants placed with a surgical template without metallic sleeves. In the test group, close sleeves were more accurate compared with open sleeves in angle (p = 0.0268) and in horizontal plan (p = 0.0477). Conclusion: With the limitations of the present study, surgical templates without metallic sleeves were more accurate in the vertical plan and angle compared to the conventional template with metallic sleeves. Open sleeves should be used with caution in the molar region only in case of reduced interarch space. Further research is needed to confirm these preliminary results.

Oro-antral communication (OAC) acts as a pathway for bacteria between the maxillary sinus and oral cavity, and is a common complication after the removal of a dental implant or extraction of a tooth from the maxillary posterior area. In the case of an untreated OAC, oro-antral fistula develops and becomes epithelialized. We aimed to introduce a treatment for OAC closure via a sinus bone grafting procedure using bone tacks and a collagen membrane with an allograft. The procedure was performed by applying an absorbable membrane made in pouch form. This membrane acted as a barrier for closing the large sinus membrane perforation. Bone tacks were used to fix the membranes. Subsequently, the maxillary sinus was filled with the allograft, and the absorbable membrane was reapplied. Primary closure was achieved by performing a periosteum-releasing incision for a tension-free suture. After 6 months, sufficient bone dimensions were gained without any occurrence of maxillary sinusitis or recurrence of OAC. Additional bone grafts and implantation could be performed to rehabilitate the maxillary posterior area. We conclude that this technique might be a useful treatment for reconstructing the maxillary posterior area with simultaneous sinus bone graft and OAC closure.

Subject. With the advent of advanced imaging technology and CAD/CAM technologies, the possibility of guided surgery has become of wide interest among implantology. The article is devoted to the use of surgical template implantation in the rehabilitation of a dental patient. It provides information about some advantages and disadvantages of the digital protocol in comparison with traditional dental implantation. The main stages of navigation surgery in a clinical case are described. Goal. To evaluate the actual clinical advantages and disadvantages of dental implant placement using a surgical template compared to the traditional treatment protocol. Methodology. The literature search was conducted in scientific search bibliographic databases such as PubMed, eLIBRARY, Medline, and Google Academy. More than 384 studies up to 2014 were found under the thematic headings "Dental implantation" and "Surgical template". During the study of these works, the sample included 56 articles and literature reviews. Conclusions. Recently, implant placement using a surgical template has become a popular treatment method among dental surgeons. The study of modern literature allowed us to formulate the main advantages and disadvantages of this method. Advantages of the method: precise positioning of implants; flap-free surgery reduces the operation time and is characterized by a favorable postoperative course; integration of restoration determinants in surgical planning, which leads to a more aesthetic, functional and predictable result of prosthetics; the possibility of pre-manufacturing a prosthesis based on the planned position of the implant; simplification of the surgical procedure for the dentist. However, this method is not without its drawbacks: the surgeon's inability to visualize anatomical structures; the risk of axis and depth deviation during implant placement; requires additional digital planning.

Immediate Implant

Introduction: Immediate placement of implants in a fresh post-extraction socket is an increasingly popular and established treatment option. However, active infection in the extraction site may adversely affect the outcome of this procedure. This study was designed to assess the clinical results of immediate placement of dental implants in infected extraction sockets using a standardized protocol, which included (a) the use of an Er,Cr:YSGG laser for the decontamination of the infected socket prior to implant insertion, and (b) the utilization of an in situ hardening alloplastic bone graft substitute to augment the gap between the implant surface and the labial plate of bone. Patients and Methods: A retrospective record review was used to identify 68 patients who had implants placed as per the described protocol. A total of 126 implants were placed in 68 patients (65 implants in the maxilla, 61 implants in the mandible). The implants were loaded 136 ± 73 days (mean ± standard deviation; range: 37–400 days) after implant placement. Eight patients (16 implants) were subsequently lost to follow up. Results: 105 of the 110 implants (95.45%) placed immediately in the infected sites using the described protocol survived after prosthetic loading. Conclusion: Immediate implant placement in previously infected sites using the protocols mentioned in our study with laser decontamination of the socket, grafting with an in situ hardening alloplastic bone graft material and non-submerged healing shows a similar survival rate to the published success rates for immediate implants placed in non-infected sites.

Missing Tooth

A dental implant is the most accepted treatment option to replace the badly decayed tooth or missing tooth. The jumping gap left after the placement of the implant in the socket will require augmentation of bone graft material. In this case report, the extracted root stumps are used as an autogenous tooth graft material after its preparation. And PRF is mixed with graft material for additive advantage. So, the present case report discusses the feasibility of the use of autogenous tooth graft material along with PRF for the better osseointegration of the implant.
