Clinical benefits and effectiveness of static computer-aided implant surgery compared with conventional freehand method for single-tooth implant placement.

PURPOSE: To evaluate the effectiveness of static computer-aided surgery technique with the conventional freehand method to assess the role of the surgical template in terms of duration of operation and postoperative pain levels. METHODS: Total of 26 implants were placed: 13 using tooth-supported surgical templates; and 13 using the conventional freehand method. Duration of the surgery was recorded for all operation sites. After implant insertion, all patients were asked to evaluate two separate visual analog scales (VAS) at regular intervals for 1 week. All patients underwent cone beam computed tomography (CBCT) evaluation to assess the depth of deviation of the planned and placed implants. RESULTS: The deviation of implants inserted using the computer-aided surgical technique and conventional freehand technique demonstrated no significant differences (P<0.05). However, the computer-aided surgery technique significantly decreased the duration of the surgery and post-op pain levels. CONCLUSION: Tooth supported surgical templates had no particular effect on the accuracy of single implant placement. Nevertheless, this procedure allows flappless surgery with minimal invasive approach, reduce operation time and post-op pain levels. If further studies with larger study samples confirm the abovementioned results, surgical templates may be recommeded even in patients with single tooth loss.

Effect of concentrated growth factor (CGF) on short-term clinical outcomes after partially impacted mandibular third molar surgery: A split-mouth randomized clinical study.

PURPOSE: The aim of this study was to evaluate the effectiveness of concentrated growth factor(CGF) on soft tissue healing and postoperative side effects following third molar surgery. METHODS: This study was designed on 60 patients as a randomized single-blind clinical trial. The predictor variable was the implementation of CGF fibrin matrix, which was categorized as CGF and non-CGF. The primary outcome variable of the study was the healing of soft tissue around the extraction socket. The secondary outcome variables were pain, swelling and trismus. Data were analyzed using the non-parametric Brunner and Langer model. Statistical significance was set at P<.001. RESULTS: Sixty patients (39 female, 21 male; mean age 25.82) with impacted mandibular third molars participated in the study. Statistical analysis revealed that there were significant differences between the control and test groups with regard to soft tissue healing, postoperative pain, swelling, and trismus (P<0.001). CONCLUSION: The application of CGF accelerates soft tissue healing and is beneficial in minimising postoperative side effects, particularly pain, swelling and trismus, after extraction of mandibular third molars. CLINICAL TRIALS NUMBER: NCT03913884.

The role of concentrated growth factor on implant stability: A preliminary study.

PURPOSE: The purpose of this preliminary study was to evaluate the effect of concentrated growth factor (CGF) on dental implant stability in type 2 bone using the resonance frequency analysis (RFA) device Smartpeg®. METHODS: The researchers carried out a prospective cohort study on a sample group composed of 12 patients (mean age=67) who required dental implants. Implant socket preparation (with and without CGF) was the primary predictor variable. In each patient, two dental implants were inserted in the anterior mandible. For the test group, one dental implant socket was covered with CGF membrane, while the other socket was prepared conventionally for the control group. Implant stability, as measured by RFA, was the outcome variable. Measurements were taken using the Ostell device at the time of implant placement and at the 1st, 2nd and 4th weeks. RESULTS: Mean implant stability quotients (ISQs) were 67.00±4.573 for the study group and 64.75±5.065 for the control group. The difference between the two groups was not statistically significant. CONCLUSION: It was found that CGF did not provide beneficial effect on dental implant stability in the early healing period in type 2 bone.

Three-dimensional bone grafting in dental implantology using autogenous bone ring transplant: Clinical outcomes of a one-stage technique.

BACKGROUND: An insufficient bone volume at the maxillary anterior region often restricts dental implant treatment and commonly leads to poor aesthetic outcomes. The defective site requires bone grafting as an initial surgical intervention before dental implant placement. In dental implantology, reconstructing osseous defects using autologous block bone grafts, biomaterials, or a combination of both is a routine surgical procedure. This study aims to evaluate the efficacy of autogenous, symphyseal, bone ring block grafts after the augmentation of defective sockets and clinical application of grafts in the maxillary anterior region with immediate insertion of a dental implant in a single surgical procedure. MATERIALS AND METHODS: The study included eight patients (five females and three males) with 12 defective sockets. The technique included removing the bone from the chin region for transplant, fitting the three-dimensional bone rings in the prepared sockets of the maxillary anterior region, and screwing the dental implants through the rings. Patients underwent postoperative clinical examinations every day during the first week and then every month for 6 months. RESULTS: In two cases, the wound dehisced but healed by secondary intervention during the follow-up period. In one case, the ring graft sequestrated because of infection in postoperative month 2, the osseous defect was reconstructed with biomaterials. The remaining cases healed with no infection, and no other case failed during the first year. CONCLUSION: This technique showed promising and advantageous results, and thus, could be an alternative treatment to other autogenous graft techniques, particularly for defective sockets.

The treatment of a localized osseous sequestrum with porous bone mineral in combination with a collagen membrane and resorbable bone pins.

The ultimate goal of periodontal therapy should not be limited to the establishment and maintenance of periodontal health. The potential regeneration of the hard and soft periodontal tissues lost due to disease also should be considered. This case presentation evaluated a new surgical technique for the treatment of a variety of localized bone defects, utilizing porous bone mineral in combination with collagen membrane and resorbable bone pins.

Peripheral adenomatoid odontogenic tumor: birth of a term.

The terminology of adenomatoid odontogenic tumor had been reviewed and the different names for this lesion used over the course of time have been listed. A case of peripheral adenomatoid odontogenic tumor which occurred on the gingiva of the right maxillary central incisor of a 4-year-old girl is reported.

Herpetic whitlow.

This paper describes a case of transmission of herpetic whitlow to the index finger of a dental student from a patient with herpes simplex virus. The recognition of intraoral viral infections in patients is important because these viruses have serious implications for health care providers. Rubber gloves must be worn when patients with primary or secondary herpetic lesions are treated. Asymptomatic permanent herpes virus carriers must also be treated with appropriate precautions.

Odontoameloblastoma: report of a case.

Ameloblastic odontoma is a mixed odontogenic tumor, which is characterized as being extremely rare, displaying aggressive clinical behavior, resembling a mixed radiopaque and radiolucent radiographic appearance and containing both ameloblastoma and a composite odontoma. An eleven-year-old boy complaining of the edentulous area at the anterior maxilla, was seen at the Department of Oral Surgery of Ege University Dental Faculty. The lesion presented a radiopaque and radiolucent features on panoramic radiogram. Locally operated lesion was diagnosed as ameloblastic odontoma, because it contains islands of ameloblastoma with calcified dental structures as odontoma. The patient was followed-up for 7 years and no recurrence was seen. This case is presented because of its rarity, early detection in an edentulous area of a child, and the successful choice of treatment.
