Book Description
Background: Virtual planning and subsequently guided implant placement with a surgical template allows for flapless surgery. However, rising a flap can often not be avoided due to insufficient bone volume and mucosal quality. The use of pilot drill templates combines the advantages of preoperative virtual implant planning and the possibility of additional surgical augmentative procedures with a conventional flap. However, little data is available comparing the time needed to perform these placement methods.Aim/Hypothesis: To compare the duration of oral implant placement between free-hand (with flap), partially guided (with flap) and fully guided (flapless) surgical approaches. The null-hypothesis was that the distribution of time duration would be the same across the three methods.Material and Methods: A controlled in-vitro study with 60 identical maxillary models (3D printed polylactic acid filament) missing the teeth 15 and 24/25/26 (FDI) was performed. Based on a cone beam tomography and a surface scan an ideal virtual implant planning was prepared for the three positions 15 (length/diameter 13mm/4.3mm), 24 (13mm/4.3mm) and 26 (10mm/4.3mm). Twenty dentists viewed this specific planning and subsequently performed the placement of 3 implants per model and approach: A) free hand (no surgical template, with flap), B) pilot-drilling (NobelGuide tooth supported template, 2.0mm sleeve, with flap), C) fully-guided (NobelGuide tooth supported template, 4.3mm sleeve, flapless). Non-parametric methods were used for statistical comparison of the time duration between the approaches.Results: The mean time duration for placement of the 3 implants (15, 24, 26) was significantly different between the three approaches (Kruskal-Wallis Test p

Book Description
BackgroundThree-dimensional preoperative implant planning may help to achieve a more predictable postoperative implant position, minimizing anatomical risks and unfavorable prosthodontic outcomes. While different studies investigated the accuracy of computer-assisted implant placement with static CAD/CAM fabricated surgical templates, information on completely free hand and partially guided approaches is limited.Aim/HypothesisTo compare the postoperative implant position with the virtually planned using free hand, pilot drill and fully guided surgical approaches. The hypothesis was that there would be no differences in the accuracy between the 3 surgical protocols.Material and MethodsA controlled in-vitro study with 60 identical maxillary models (3D printed, polilactid) missing the teeth 16, 15, 24, 25, 26 and 27 was performed. The model and tooth setup were digitized with a cone beam computerized tomography (CBCT) and laboratory surface scan, and superimposed using SmartFusion technology. The study coordinator planned the ideal positions for the implants 15, 24 (13/4.3mm) and 26 (8/4.3mm) with the NobelClinician software. Twenty surgeons viewed this ideal planning and placed totally 180 implants using 3 protocols: A) free hand: mentally guided 2/3.5/4.3mm osteotomies (OST) and implant placement (IP), B) pilot drill: template-guided 2mm OST (tooth supported NobelGuide template, 2mm sleeve) combined with free-hand 3.5/4.3mm OST and IP, C) fully guided: template guided OST and IP (tooth supported NobelGuide template, 2/3.5mm inserts with 4.3mm sleeve). Three-dimensional differences between the digitized postoperative and planned implant positions were measured.ResultsFor the implant protocols A (free hand) vs B (pilot drill) vs C (fully guided) the mean absolute differences (u00b1 SD; range) between the postoperative and the virtually planned implant positions were 1.1mm (u00b10.8; 0.2-4.7) vs 0.7mm (u00b10.4; 0.1-1.8) vs 0.5mm (u00b10.3; 0-1.6) at the entry point, 1.5mm (u00b10.7; 0.3-3.2) vs 1.2mm (u00b10.6; 0.4-2.5) vs 0.7mm (u00b10.4; 0.1-2.1) at the tip, and 5.1u00b0 (u00b14.5; 0.1-27.3) vs 5.0u00b0 (u00b13.2; 0.7-19.0) vs 1.9u00b0 (u00b11.6; 0.1-8.6) for the angle. Statistical comparisons (ANOVA, Bonferroni correction) of the mean values revealed significant differences at the entry point, i.e. A vs B (p

Book Description
This book explores, in a comprehensive and systematic manner, Surgical Research methodologies to the design and development of investigational studies in the field of implant-based oral rehabilitation. Such studies are linked in a chain binding in vitro, in vivo, ex vivo, and digital evaluations. An ambitious objective consists in exposing how investigators can generate and deliver knowledge by capturing synergy coming from preclinical and clinical trials. Accordingly, throughout the book, translational aspects are closely scrutinized. The opening chapters consider materials, methods and procedures for preclinical and clinical studies in which approaches and models are extensively described. The focus then moves to the process by which application of histology, biomechanics, biomarkers, cellular/molecular biology, and imaging technologies lead to new results and consequently novel treatment concepts in implant dentistry, implant borne prosthetic rehabilitations and the replacement or regeneration of tissues. Finally, the exciting opportunities afforded by the digital world are addressed. This book shall be a valuable resource and time-saving tool for a wide audience of researchers, students, practitioners, and academics.

Book Description
Volume 10 of the ITI Treatment Guide series starts out with the most recent statements and recommendations of the 5th ITI Consensus Conference, followed by a detailed protocol for the evaluation and treatment planning of patients with esthetic demands requiring single-tooth replacement with a dental implant. Various surgical situations commonly encountered in the esthetic zone will be presented and recommendations on their treatment will be provided. In addition, the clinical management of the planned implant site before and after placement through the use of provisional prostheses, laboratory communication, abutment design, restorative material selection, and delivery will be examined. This volume of the ITI Treatment Guide series provides a comprehensive, evidence-based approach to single-tooth replacement in the esthetic zone, from consultation to follow-up, with a focus on current treatment modalities and on the materials that present-day implant dentistry has to offer. The ITI Treatment Guide series is a compendium of evidence-based implant-therapy techniques and procedures for daily practice. Written by renowned clinicians and supported by contributions from expert practitioners, the ITI Treatment Guides provide a comprehensive overview of various clinical options. The management of different clinical situations is discussed with an emphasis on sound diagnostics, evidence-based treatment concepts, and predictable treatment outcomes with minimal risk to the patient.
