Aims: This in silico study aimed to investigate the effect of implant–abutment contact surfaces on stress generation Morse taper implants under oblique loading. Materials and methods: Three-dimensional finite element models Bone-Level Tissue-Level were simulated with Standard Partial contacts between abutment implant. The dimensional parameters followed ISO 14801 guidelines, an load 300 N was applied implants. von Mises acquired. Results: design showed a significant difference level when...
New monolithic multi-layered zirconia restorations are gaining popularity due to their excellent aesthetic properties. However, current knowledge of these newest multi-layer ceramics in terms mechanical properties is scarce. Three monolithic, materials (Katana, Kuraray Noritake, Japan) were selected for comparison: High Translucent Multi-layered (HTML), Super (STML) and Ultra (UTML). Fifteen specimens per group cut from pre-sintered blocs each the four layers (L1, L2, L3, L4) different...
Purpose The aim of this ex-vivo study was to evaluate the load capacity direct or indirect endodontically restored maxillary central incisors with Class III defects, without glass-fiber posts. Materials and methods Seventy-two extracted human were treated bi-proximal cavities prepared. Specimens randomly allocated six groups (n = 12): restoration composite (C); additional post (CP); ceramic veneer (V), (VP), crown (Cr), (CrP). exposed thermomechanical loading (TML: 1.2 million cycles, 1 50...
The purpose of this clinical study was to assess the feasibility forced orthodontic extrusion with Tissue Master Concept retain subgingivally fractured teeth as abutments for which extraction and replacement would be equal treatment opportunities. Participants were recruited from a group consecutive patients in need prosthodontic rehabilitation. In total, 36 deeply destroyed 31 underwent forces exceeding 50 g reestablish biologic width ensure 2-mm dentin-ferrule design prior single-crown...
For restoration of extensively damaged teeth preprosthetic treatment measures are necessary. Crown lengthening and extrusion affect the prospective crown-root ratio (CRR). The subject this in vitro study was to compute CRRs for both approaches. 120 human maxillary central extracted incisors were measured. Measurements calculated five groups: C (control), E-2 mm (extrusion 2 mm), E-4 4 CL-2 (crown CL-4 mm). Tooth (TL), root (RL), crown lengths (CL) measured from mesial (m) facial (f)...
Maintaining and restoring teeth exhibiting subgingival or even subcrestal defect extensions represent a common problem in daily practice. Such are often deemed "unrestorable" due to significant hard tissue loss locations violating the biologic width. In order achieve sufficient 2-mm-ferrule design reestablish width, both surgical crown lengthening orthodontic extrusion have been suggested. However, has negative effect on attachment level of adjacent as well esthetic disadvantages...
To compare the planned implant position (PIP) with transferred (TIP) after fully guided placements in single-tooth gaps.Dental were using two different systems (Camlog Screw-Line [C-SL] and Straumann Bone Level Tapered [S-BLT]), planning software programs (SMOP coDiagnostiX). All implants placed according to protocols, intraoral scans performed intraoperatively. For comparison of PIP TIP, scan data imported Geomagic Control X (GCX) accuracies evaluated. Deviations reported a coordinate...
To assess clinical, radiological and esthetic outcomes of restorations supported by root-analogue implants (RAIs) or roots severely damaged teeth after forced orthodontic extrusion (FOE).Clinical data regarding milled one-piece (titanium/zirconia zirconia abutments) RAIs (REPLICATE™ System) FOE were recorded retrospectively evaluated for 40 patients two investigators. Strict inclusion exclusion criteria applied. Functional assessed n = 20 pre-molars anterior via comparison radiographic...
The restoration of severely damaged teeth challenges dental practitioners because defects are often located at the subcrestal level. In these cases, surgical crown lengthening or orthodontic extrusion procedures deemed necessary to maintain biologic width and respect a sufficient ferrule design after preparation. Considering negative effects invasive therapy-such as reduction alveolar bone support neighboring teeth-forced might be valid therapeutic alternative. This clinical case report...
In cases of severely compromised teeth, dental practitioners are confronted with the therapeutic decision whether to restore a tooth or replace it an implant. Comparative scientific evidence on patient perception both treatment approaches is scarce. The subject this prospective clinical study was compare oral health-related quality life (OHRQoL) between two groups: restoration destroyed teeth after orthodontic extrusion (FOE) versus extraction and implant-supported single crown (ISC). A...
Abstract Objectives To assess clinical, radiological and esthetic outcomes of prosthodontic rehabilitations supported by root-analogue implants (RAIs) or roots severely damaged teeth after forced orthodontic extrusion (FOE). Materials Methods Clinical data regarding RAIs FOE were recorded retrospectively evaluated for 40 patients two independent investigators. Functional assessed n = 20 pre-molars anterior via comparison radiographic digital images applying the novel Implant Prosthodontic...
Abstract Objectives Clinical data on retaining extensively damaged teeth using forced orthodontic extrusion followed by restorative rehabilitation are scarce, and economic evaluations basically absent. Based a clinical study we performed health evaluation of this treatment approach. Materials Methods In convenience sample individuals recruited from routine care, were orthodontically extruded prior to restoration. Patients up for 6 years. Our outcome was tooth retention time. Direct medical,...
Abstract Introduction For restoration of extensively damaged teeth preprosthetic treatment measures are necessary. Surgical crown lengthening and orthodontic extrusion affect the prospective crown-root ratio (CRR). Evidence on true values CRR is scarce. The subject this in-vitro study was to compute CRRs for both approaches. Methods 120 human maxillary central extracted incisors were measured. Measurements calculated five groups: C (control), OE-2mm (orthodontic 2mm), OE-4mm 4mm), SCL-2mm...
