Aim: The aim of this study was to evaluate the treatment outcome of immediately restored mini-implants with a diameter of 2.5 mm one year after their use for rehabilitation of congenitally absent maxillary lateral incisors. Methodology: A total of 30 mini-implants (narrow ridge 2.5) were inserted in 23 patients (13 females, 10 males) with a mean age of 21.6 years (range: 16–38 years) at the implant center of Damascus University. The implants replaced congenitally absent maxillary lateral incisors. All implants were immediately restored with a non-functional provisional acrylic crown. The abutment part of the implant was prepared before crown cementation. The ceramic permanent crown was placed after three months. A health implant scale was chosen to evaluate implant success. A periapical standard X-ray was taken immediately upon bonding of the temporary crown as well as after one year of loading. Proximate bone loss was measured using Canvas 9 (ACD, 2004). Results: No implant was lost; thus, the one-year implant survival was 100%. Optimal survival was 93.6%. A statistically significant mean marginal bone loss was observed between baseline and 12 months (mesial: 1.06 ± 0.55 mm; distal: 1.05 ± 0.53 mm). Conclusion: A high one-year survival rate was documented for management of congenital missing maxillary lateral incisors using immediately loaded mini-implants, and these implants therefore provide a good alternative treatment option.

Aim: Surgical treatment of patients with severe thrombocytopaenia (<50,000 platelets/mL) is a major problem for dentists due to an increased risk of bleeding. To reduce post-extraction haemorrhage, we tested a new approach using a platelet concentrate and compared its outcomes with those of routine platelet transfusion. Methodology: Sixty-six patients with a platelet count between 29,000 and 46,000/mL were included in the study. Each patient was to undergo at least two sessions for the extraction of teeth; in one session the patients received a platelet transfusion before the extraction and in the other the post-alveolar sockets were treated with Plasma Rich in Growth Factors (PRGF). Patients were evaluated after 0.4, 1, 3 and 7 days to assess bleeding and haematoma. Results: Patients treated with PRGF consistently exhibited a statistically significant reduction in post-extraction bleeding, hematoma and need for re-intervention. There is ample evidence that application of PRGF in the post-alveolar socket markedly reduced the risk of haemorrhage and associated complications in all patients. Conclusion: PRGF concentrate is recommended for the treatment of thrombocytopaenic patients due to its remarkable ability to stimulate healing while greatly reducing side effects, such as bleeding and haematoma.

Aim: To demonstrate three-dimensional virtual modeling of a cleft lip and palate patient. Methodology: Traditional two-dimensional treatment planning modalities are often inadequate. Developing technology has enabled the virtual modeling of cleft lip and palate patients. Mimics software was used to demonstrate how to construct such a model. Conclusion: We are now able to model cleft lip and palate patients in three dimensions. How to cite this article:  Karadede İ, Adıgüzel Ö, Özer T, Bilgiç F, Özhal İzol R.

A study of the implant–abutment connection is of great importance because it is the primary determinant of the strength and stability of an implant-supported restoration, which, in turn, determines the restoration’s prosthetic stability. Traditionally, Brånemark’s external hexagon has been used, but significant complications, such as abutment screw loosening, rotational misfit at the implant–abutment interface, and microbial penetration have led to modification of the external hexagon and the development of internal implant–abutment connections. In this review, we describe various implant–abutment connections that have evolved over time from the traditional external hexagon.  How to cite this article:  Alharissy M, Dayoub S.
