Abstract Bone healing around dental implants follows the pattern and sequence of intramembraneous osteogenesis with formation woven bone first all followed later by parallel‐fibered lamellar bone. apposition onto implant surface starts earlier in trabecular than compact While new may be found on 1 week after installation, remodeling at between 6 12 weeks continues throughout life. also involves bone–implant interface, thus transiently exposing portions surface. Surface modifications creating micro‐rough surfaces accelerate osseointegration process titanium implants, as demonstrated numerous animal experiments. Sandblasting acid‐etching currently regarded gold standard technique to create surfaces. Chemical modifications, resulting higher hydrophilicity, further increase speed titanium‐zirconium both animals humans. zirconia alumina‐toughened have an influence osseointegration, some types reach high bone‐to‐implant contact values animals. Although often discussed independently each other, characteristics, such topography chemistry, are virtually inseparable. Contemporary, well‐documented systems surfaces, placed properly trained experienced clinicians, demonstrate long‐term survival rates. Nevertheless, failures do occur. A low percentage diagnosed peri‐implantitis 10 years function. In addition, a number seem lost for primarily reasons other biofilm‐induced infection. Patient factors, medications interfering immune system cells, element contributing continuous loss should therefore monitored studied greater detail.

Clinical relevance of dimensional bone and soft tissue alterations post‐extraction in esthetic sites

Periodontology 2000, Год журнала: 2016, Номер 73(1), С. 73 - 83

Опубликована: Дек. 21, 2016

Abstract The key to achieving pleasing esthetics in implant dentistry is a thorough understanding of the biological processes driving dimensional bone and soft tissue alterations post‐extraction. aim present report first characterize extent changes post‐extraction second identify potential factors influencing preservation order facilitate successful treatment outcomes. facial wall thickness has been identified as most critical factor resorption can be used prognostic tool sites at risk for future loss subsequent tooth extraction. Clinical studies indicated that thin phenotypes exhibiting 1 mm or less revealed progressive with vertical 7.5 mm, whereas thick showed only minor 1.1 mm. This contrast alterations. Thin spontaneous thickening after flapless extraction by seven, no significant dimensions 8 weeks healing. In limited rate, immediate placement may considered. If such ideal conditions are not present, other timing protocols recommended achieve predictable esthetics. Socket techniques ridge utilizing different biomaterials and/or barrier membranes often result better maintenance volumes, although inevitable process modeling cannot arrested. summary, knowledge events should integrated into comprehensive plan limit maximize esthetic

Abstract This state‐of‐the‐art review presents the latest evidence and current status of autogenous soft tissue grafting for augmentation recession coverage at teeth dental implant sites. The indications predictability free gingival graft connective (CTG) techniques are highlighted, together with their expected clinical esthetic outcomes. CTGs can be harvested from maxillary tuberosity or palate different approaches that have an impact on quality patient morbidity. influence thickness keratinized width also discussed.

Peri‐implant soft tissue phenotype modification and its impact on peri‐implant health: A systematic review and network meta‐analysis

Journal of Periodontology, Год журнала: 2020, Номер 92(1), С. 21 - 44

Опубликована: Июль 25, 2020

Abstract Background The peri‐implant soft tissue phenotype (PSP) encompasses the keratinized mucosa width (KMW), mucosal thickness (MT), and supracrestal height (STH). Numerous approaches to augment volume around endosseous dental implants have been investigated. To what extent PSP modification is beneficial for health has subject of debate in field implant dentistry. aim this systematic review was analyze evidence regarding efficacy augmentation procedures aimed at modifying their impact on health. Methods A comprehensive search performed identify clinical studies that involved reported findings KMW, MT, and/or STH changes. effect intervention also assessed. Selected articles were classified based general type surgical approach increase PSP, either bilaminar or an apically positioned flap (APF) technique. network meta‐analysis including only randomized‐controlled trials (RCTs) reporting outcomes conducted assess compare different techniques.

Dimensional alterations of the facial soft and bone tissues following tooth extraction in esthetic zone play an essential role to achieve successful outcomes implant therapy. This prospective study is first investigate interplay between tissue dimensions underlying anatomy during 8-wk healing period. The analysis based on sequential 3-dimensional digital surface model superimpositions using impressions cone beam computed tomography Soft thickness thin thick phenotypes at was similar, averaging 0.7 mm 0.8 mm, respectively. Interestingly, revealed a 7-fold increase after period, whereas phenotypes, remained unchanged. observed spontaneous thickening resulted vertical loss only 1.6 which concealed resorption 7.5 mm. Because thickening, no significant differences were detected total 2, 4, 6, 8 wk. More than 51% these dimensional occurred within 2 wk healing. Even though conceals pronounced pattern by masking true deficiency, offers advantages for subsequent regeneration therapies sites with high demand (Clinicaltrials.gov NCT02403700).

Abstract Background The health of peri‐implant soft tissues is one the most important aspects osseointegration necessary for long‐term survival dental implants. Purpose To review process tissue healing around osseointegrated implants and discuss maintenance requirements as well possible short‐comings integration. Materials Methods Literature search on involved in osseointegration, currently available treatment modalities was performed a brief description each provided. Results interface has been shown to be less effective than natural teeth resisting bacterial invasion because gingival fiber alignment reduced vascular supply make it more vulnerable subsequent disease future bone loss And we summarized common procedures which have preventing peri‐implantitis progression clinical techniques utilized regenerate with advanced cases peri‐implantitis.
