Introduction:Zirconia is often used for implant abutments for esthetics. The aim of this clinical study was to compare the effects of zirconia and metal abutments on periimplant soft tissue. Materials and Methods:Ten maxillary anterior implant patients, 5 with metal abutments and 5 with zirconia abutments, were enrolled in this trial. The soft tissue around the implant abutments was evaluated by 2-dimensional laser speckle imaging and thermography. The blood flow in soft tissue around natural…

TLDR
Comparing the stresses on morse taper implant systems under parafunctional loading in different abutment materials using three-dimensional finite element analysis (3D FEA) decreases von Mises stress values in abutments and implants, however, these values may exceed the pathological limits in bruxism patients.
Enhancement of Gingival Tissue Adherence of Zirconia Implant Posts: In Vitro Study
TLDR
Treatment of zirconia can lead to double interface stiffness, invariant viscostiffness and material memory values, which is beneficial in preventing bacterial contamination in dental implants, and suggests TiO2-coated zIRconia abutments may have a significant clinical benefit for prevention of the bacterial contamination.
Bone response to functionally loaded, two‐piece zirconia implants: A preclinical histometric study
TLDR
The present two-piece zirconia implant showed a similar bone integration compared to the titanium implant with similar surface morphology after 4 and 16 weeks of loading.
COMPARISON OF PERI-IMPLANT CLINICAL INFLAMMATORY PARAMETERS AMONG SCREW RETAINED CAD/CAM METAL BAR AND ZIRCONIA BAR FOR PATIENTS WITH RECONSTRUCTED MANDIBLES
TLDR
Zirconia metal bar is considered more biocompatible than the metal bar in patients with reconstructed mandibles that were rehabilitated with implant retained mandibular removable partial overdenture concerning the peri implant gingival index and probing depth.
Oral Tissue Interactions and Cellular Response to Zirconia Implant-Prosthetic Components: A Critical Review
TLDR
Dental devices manufactured from ZrO2 are structurally and chemically stable with biocompatibility levels allowing for safe and long-term function in the oral environment and provide encouraging prospects for rapid bone adhesion.
Zirconia compared to titanium dental implants in preclinical studies-A systematic review and meta-analysis.
TLDR
Not only material characteristics but predominantly animal species and study protocols can significantly influence the outcomes, and titanium tended to show a faster initial osseointegration process compared to zirconia.
Implant Supported Fixed Dental Prostheses Using a New Monotype Zirconia Implant—A Case Report
TLDR
The present case reports a fixed implant-supported reconstruction of a large edentulous space with compromised local bone conditions using new monotype zirconia dental implants with a micro-rough surface topography.
Combining a single implant and a veneer restoration in the esthetic zone.
TLDR
A well-planned single implant and a ceramic veneer restoration was able to fulfill the patient's esthetic expectations and manage the occlusal forces and to mimic the shade and shape of the adjacent teeth.
Morphological Evaluation of Soft Tissue Augmentation Using Porous Poly-DL-Lactic Acid With Straight Holes
TLDR
Porous poly-DL-lactic acid (PDLLA) contributed favorable prognosis for soft tissue and a wider hole was associated with increased connective tissue and blood vessel areas.

Experimental zirconia abutments for implant-supported single-tooth restorations in esthetically demanding regions: 4-year results of a prospective clinical study.
TLDR
Zirconia abutments offered sufficient stability to support implant-supported single-tooth reconstructions in anterior and premolar regions and were favorable to peri-implant hard and soft tissue reaction as well as fracture resistance over time.
Zirconia and titanium implant abutments for single-tooth implant prostheses after 5 years of function in posterior regions.
TLDR
The medium-term survival of Zr abutments in posterior regions was comparable with that of Ti abutment, and long-term evaluations are needed to confirm this finding.
Five-year results of a randomized controlled clinical trial comparing zirconia and titanium abutments supporting single-implant crowns in canine and posterior regions.
TLDR
There were no statistically or clinically relevant differences between the 5-year survival rates, and the technical and biological complication rates of zirconia and titanium abutments in posterior regions.
The mucosal barrier at implant abutments of different materials.
TLDR
It was demonstrated that the soft tissue dimensions at Ti- and ZrO(2) abutments remained stable between 2 and 5 months of healing, but at Au/Pt-alloy abutment sites, however, an apical shift of the barrier epithelium and the marginal bone occurred between2 and 5 years of healing.

TLDR
Zirconia abutments for single-implant crowns seem to demonstrate good short-term technical and biological results.
Clinical use of alumina-toughened zirconia abutments for implant-supported restoration: prospective cohort study of survival analysis.
TLDR
Alumina-toughened zirconia abutments are likely to exhibit excellent long-term survival in clinical use for fixed restorations and to evaluate the effects of several clinical variables on these rates.
Two-Dimensional Real-Time Blood Flow and Temperature of Soft Tissue Around Maxillary Anterior Implants
TLDR
The results suggest that simultaneous measurements of soft-tissue blood flow and temperature is a useful technique to evaluate the microcirculation of soft tissue surrounding implants.
Ceramic implant abutments used for short-span fixed partial dentures: a prospective 2-year multicenter study.
TLDR
The 2-year results have been very encouraging for CerAdapt abutments supporting short-span fixed partial dentures (FPDs), however, ceramic materials tend to undergo static fatigue, and it is therefore important to wait for the 5- year results before making any more definite statement about the long-term prognosis.

The mucosal attachment at different abutments. An experimental study in dogs.
TLDR
The findings from the analysis demonstrated that the material used in the abutment portion of the implant influenced the location and the quality of the attachment that occurred between the periimplant mucosa and the implant.
