Abstract Introduction Studies demonstrated that the accuracy of intra‐oral scanners can be compared with conventional impressions for most indications. However, little is known about their applicability to take multiple implants. Aim The aim this study was evaluate four when applied implant in edentulous jaw. Material and methods An acrylic mandibular cast containing six external connection implants (region 36, 34, 32, 42, 44 46) PEEK scanbodies scanned using scanners: Lava C.O.S. 3M True...

Abstract Objectives: Retrospectively evaluate the survival, radiographic and peri‐implant outcome of single turned Brånemark ™ implants after at least 16 years. Materials methods: From 134 patients ( C‐group ), 101 could be contacted concerning implant survival 50 (59 remaining implants) were clinically examined I‐group ). Marginal bone level was radiographically measured from implant–abutment junction baseline (=within 6 months abutment connection) 1–4, 5–8 16–22 years post‐operatively....

Nanostructure modification of dental implants has long been sought as a means to improve osseointegration through enhanced biomimicry host structures. Several methods have proposed and demonstrated for creating nanotopographic features; here we describe nanoscale hydroxyapatite (HA)-coated implant surface hypothesize that it will hasten its quality relative non-coated implants. Twenty threaded titanium alloy implants, half prepared with stable HA nanoparticle grit-blasted, acid-etched,...

Although histology has proven to be a reliable method evaluate the ossoeintegration of dental implant, it is costly, time consuming, destructive, and limited one or few sections. Microcomputed tomography (µCT) fast delivers three-dimensional information, but this technique not been widely used validated for histomorphometric parameters yet. This study compared µCT histomorphometry by means evaluating their accuracy in determining bone response two different implant materials. In total, 32...

Abstract Background The All‐on‐4® concept is widely applied for full‐arch rehabilitations, using two tilted and axially loaded implants in order to overcome anatomical constraints. Purpose aim of this study was assess the survival individual success immediately with an All‐on‐4 screw‐retained prosthetic bridge fully edentulous mandibles or maxillae over up 3 years. Materials Methods In total, 20 patients atrophic jaws (9 maxillae, 11 mandibles) were treated computer‐guided flapless surgery...

The aim of this study was to evaluate the accuracy full-arch digital impressions when compared conventional impressions, performed on abutment or implant level.One resin cast with six implants and another abutments were scanned Primescan v5.1 (PS51), v5.2 (PS52), Trios 3 (T3), 4 (T4). Additionally, (A) made, poured in gypsum, digitized using a lab scanner (IScan D104i). A coordinate machine (Atos, GOM, Braunschweig, Germany) used generate reference scan both casts. For all scans, position...

The aim of this in vitro study was to evaluate and compare the fit fracture load 3D printed milled composite onlays. An onlay preparation a lower right molar duplicated 28 times by means printing (Model 2.0, Nextdent, systems, Soesterburg, Netherlands). Fourteen onlays were (Brilliant Crios, Coltène, Whaledent AG, Switzerland) 14 (Nextdent C&B MHF, marginal internal evaluated using silicone-replica technique. For each impression, two sections made silicone material. Each slice photographed...

To promote consensus on implant dentistry university education in Europe, a workshop amongst teachers and opinion leaders was organised 2008. As result, guidelines both under- postgraduate were issued. This study aims to investigate the current status of teaching impact recommendations for assessment, 5 years after first consensus. Finally, this report attempts identify future directions within discipline.An online survey distributed 105 academic 52 questionnaires returned (response rate...

Long term studies on single implants are scarce and merely focus clinical response parameters, complications bone remodelling. The objective of this retrospective case series was to assess alterations in soft tissue levels aesthetics over a 16-22 year period periodontally-healthy patients.Patients who had received turned implant the anterior maxilla/mandible at Dental Specialist Clinic Malmö between 1987 1993 were invited for re-examination basis number inclusion criteria. Both neighbouring...

The International Journal of Oral & Maxillofacial Implants e171 T he internal-connection implant has increased its share the oral market as a result better sealing capabilities, 1 distance from osseous crest to abutment-implant interface, 2 and capacity withstand larger axial load than with flat-top (external-connection) interface. 3presentative internal systems that are currently available have shown high survival success rates, along stable marginal bone preservation. 4,5lthough dentistry...

Abstract Aim: To compare the survival and peri‐implant bone loss of implants with a fluoride‐modified surface in smokers nonsmokers. Materials methods: Patient files all patients referred for implant treatment from November 2004 to 2007 were scrutinized. All placed by same experienced surgeon (B. C.). The only inclusion criterion was follow‐up time at least 2 years. Implant assessed an external calibrated examiner (S. V.) comparing digital peri‐apical radiographs taken during recall visits...

Summary Titanium or zirconium computer‐aided design/computer‐aided manufacturing abutments are now widely used for aesthetic implant treatments; however, information regarding microscopic structural differences that may influence the biological and mechanical outcomes of different systems is limited. Therefore, characteristics connection were investigated. Optical observation scanning electron microscopy showed two internal systems, namely Astra Tech Replace Select system, materials. The...

Purpose: Commercial implants differ at macro-, micro-, and nanolevels, which makes it difficult to distinguish their effect on osseointegration. The aim of this study was evaluate the early integration 5 commercially available (Astra OsseoSpeed, Straumann SLA, Intra-Lock Blossom Ossean, Nobel Active, OsseoFix) by histomorphometry nanoindentation. Materials Methods: Implants were installed in tibiae 18 beagle dogs. Samples retrieved 1, 3, 6 weeks (n = for each time point) histologically...

ABSTRACT Introduction: The Co‐Axis® implant (Southern Implants®, Irene, South Africa) has a 12‐degree angle in the neck to overcome angulation problems. Aim: To examine bone loss, peri‐implant health, and aesthetical outcome after 1‐year follow‐up. Materials Methods: Fifteen single implants were placed 14 patients premaxilla immediately loaded with screw‐retained full ceramic crown. Periapical radiographs standardized photographs taken determine loss soft tissue changes. Plaque bleeding...
