Comparison of Implant Surgery Methods of Cortical Tapping and Cortical Widening in  Bone of Various Density: A Three-Dimensional Finite Element Study Baek YW, Lim YJ, Kim B. Comparison of Implant Surgery Methods of Cortical Tapping and Cortical Widening in Bone of Various Density: A Three-Dimensional Finite Element Study. Materials (Basel). 2023 Apr 21;16(8):3261. doi: 10.3390/ma16083261. PMID: 37110097; PMCID: PMC10146056. Abstract Purpose: The primary stability of a dental implant is critical for successful osseointegration during immediate loading. The cortical bone should be prepared to achieve enough primary stability, but not overcompressed. In this study, we investigated the stress and strain distribution in the bone around the implant induced by the occlusal force applied during immediate loading at various bone densities by the FEA method to compare cortical tapping and widening surgical techniques. Materials and methods: A three-dimensional geometrical model of a dental i...

Chrcanovic BR , Abreu MH. Survival and complications of zygomatic implants: a systematic review. Oral Maxillofac Surg. 2013 Jun;17(2):81-93. doi: 10.1007/s10006-012-0331-z. Epub 2012 May 6. PMID: 22562293. Abstract Purpose: This systematic review attempted to answer the focused questions: "What is the survival rate of zygomatic implants (ZIs)?" and "What are the most common complications related to surgery of zygomatic implants?" Methods: An electronic search without date or language restrictions was undertaken in PubMed in March 2012. Titles and abstracts from these results (n = 123) were read for identifying studies that meet the eligibility criteria. Eligibility criteria included studies reporting clinical series of zygomatic implants (ZIs). Because of the scarcity of articles with high-level grades of evidence, all articles, including studies with few case reports, were considered for inclusion. All reference lists of the selected and review studies were hand-se...
