Accuracy of dental implant placement with 3D-printed surgical templates by using Implant Studio and MGUIDE. An observational study.

AIM: The purpose of the present study was to report early surgical template-related and postoperative complications of computer-guided implant placement and to evaluate its accuracy. MATERIALS AND METHODS: Data were collected retrospectively from records of patients who had undergone computer-guided implant surgery between 2016 and 2018. Incidence of early surgical template-related and postoperative complications was recorded. Accuracy of implant placement was evaluated by comparing the data from postoperative CBCT records with that from the preoperative virtual implant planning by using appropriate image registration software. Depth, coronal, apical, and angular deviations were measured. RESULTS: A final number of 27 partially edentulous patients who received 52 implants with 31 static surgical templates were included in the study. All implants had been inserted in a fully guided manner using a flapless technique and following a one-stage approach. All implants were reported to have been successfully osseointegrated. Except for one template fracture, no other complication was recorded. The mean depth deviation was 0.57 ± 0.4 mm (95% CI 0.48 to 0.71 mm), the mean coronal deviation was 0.89 ± 0.7 mm (95% CI 0.73 to 1.07 mm), the mean apical deviation was 1.4 ± 1 mm (95% CI 1.16 to 1.71 mm), and the mean angular deviation was 2.74 ± 1.8 degrees (95% CI 2.29 to 3.26 degrees). CONCLUSION: The use of static surgical templates for fully guided implant placement demonstrated acceptable clinical performance. However, there are some factors affecting accuracy that should be considered during implant planning and surgery for further improvement of the technique.

Disease phobia in patients with temporomandibular joint pain assessed by the Illness Attitude Scale.

UNLABELLED: Disease phobia refers to a psychological state when the person continuously thinks that he/she is sick and improvement from the condition is impossible. Disease phobia in patients suffering from pain, secondary to temporomandibular disorders (TMDs), is usually the consequence of long-term problems; diagnosis and treatment of this group is a real challenge for healthcare professionals. AIM: The purpose of this prospective study was to objectively evaluate the role of Illness Attitude Scale (Kellner or IAS) in measuring cancerophobia and heart disease phobia in patients suffering from pain, as a consequence of TMDs. SUBJECTS AND METHODS: The cohort included 22 patients with TMDs who underwent evaluation of these phobias; pain was acute in 7 and chronic in 15. The patients were asked to complete the "Kellner" questionnaire, and this was followed by full clinical examination of the temporomandibular region. RESULTS: When measuring the correlation between the cancerophobia and heart disease phobia patients, the outcome was found significant in the total cohort, p < 0.01. Comparisons were carried out in the chronic group (n = 15) and was significant (p = 0.034 and r = 0.549); while in the acute group no significance was identified. CONCLUSION: Cancerophobia and heart disease phobia in TMD patients are factors that need to be taken in consideration when managing chronic pain in this group.

Radiographic evaluation of bone regeneration after the application of plasma rich in growth factors in a lower third molar socket: a case report.

A 42-year-old Mediterranean male presented complaining of inability to sustain good oral care at the posterior aspect of the lower right jaw. The main problems were food impaction in the area and the subsequent malodor. The patient reported remarkable medical history. Clinical examination revealed local erytherma with noticeable bone defect distal to the second molar with obvious defect in the mesial wall of the third molar; the penetration depth was found to be up to 6 mm.Radiological evaluation confirmed the defect and it was attributed to the mesioangularly partially impacted lower third molar. It was decided that third molar should be extracted and concentrate of the patient's growth factors (PRGF) to be applied into the bony defect to stimulate bone regeneration and promote healing.The third molar tooth was, then, removed surgically and the PRGF, which was prepared preoperatively, was implanted in the socket. At the first postoperative day, moderate pain was the main complaint and was controlled by NSAIDs. One week postoperatively, the sutures were removed and there was good tissue healing on examination.On the fiftieth postoperative day, radiographic evaluation took place and showed noticeable enhancement of density and radio-opacity in the third molar socket area, in comparison with the baseline image. Further, clinical examination showed significant reduction of periodontal pocketing and evidence of new bone formation.In conclusion, PRGF was very successful in stimulating bone regeneration and promote healing following dental extraction.
