ABSTRACT
PURPOSE: The aim of this prospective clinical trial was to assess clinical, radiological, and esthetic outcomes of immediate-loaded post-extractive implants after 1 year of follow-up. MATERIALS AND METHODS: Twenty-four consecutive patients (15 females and nine males) with a mean age of 47.27 years (range 35-65) requiring single-tooth extraction in the maxillary or mandibular anterior or premolar areas were enrolled. Twenty-five NobelActive implants (Nobel Biocare, Göteborg, Sweden) were placed and loaded immediately after tooth extraction. The definitive prosthetic restoration was delivered 6 months later. Clinical parameters, marginal bone loss, as well as, pink and white esthetic scores (PES and WES) were evaluated at 3, 6, and 12 months after implant placement. RESULTS: After 12-month follow-up period, a success rate of 91.67% was reported: Two of the 25 initially placed implants were lost after 4 weeks due to lack of osseointegration. The mean marginal bone loss after 1-year follow-up was 0.383 (SD ± 0.749) at mesial site and 0.278 (SD ± 0.595) at distal site. No statistically significant changes in the full-mouth plaque score (FMPS) and in the full-mouth bleeding score (FMBS) were observed from baseline to 12 months. The mean total PES/WES was 17.13 ± 1.91 (range: 13-20). None of 23 implants had an overall score <12 (threshold of clinical acceptability). CONCLUSION: Within the limitations of the present study, when careful patient selection and strict clinical protocol are observed, the immediate placement and loading of a single NobelActive(™) implant in a fresh extraction socket may be considered a valuable and predictable option in terms of implant success as well as hard and soft tissues stability.

Leiomyoma is a benign smooth muscle tumour, that occurs most frequently in the uterine myometrium, gastrointestinal tract, skin and lower extremities of middle-aged women. Leiomyomas are uncommon in the oral cavity, but in this location are usually localized on the tongue, lips and palate. Most lesions are asymptomatic, although occasional tumours can be painful. The diagnosis is mainly determined by histological studies due to its unspecific clinical appearance.The purpose of this article is to present a case report of 49-year-old male patient with a lesion of the lower lip. After surgical resection hematoxylin-eosin staining confirmed the diagnosis of leiomyoma.
ABSTRACT
Many articles have detailed local accidents and complications in dental implant treatment. Comparisons of the data they report are not always easy because different criteria have been followed in the various classifications and there is confusion between the terms accident and complication. The aim of this paper is to propose a classification that considers the timing of the events and makes a distinction between the two terms. Accidents are events that occur during surgery, and complications are any pathologic conditions that appear postoperatively. The proper diagnostic procedures and surgical techniques for their prevention and treatment are also described.
