Measurement of the interface of external connection implants with metal or zirconia abutments under scanning electron microscopy

RGO: Revista Gaúcha de Odontologia
Objective Microgap at the implant–abutment interface is a critical factor that may influence both survival- and success rates of dental implants. Several studies have found that the shape of the abutment and implant, the kind of connection between the ...

Crestal approach for repair of oroantral bone defects and subsequent implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.

Salivary bacterial leakage into implant-abutment connections: preliminary results of an in vitro study [PDF]

, 2016
OBJECTIVE: The occurrence of bacterial leakage in the internal surface of implants, through implant-abutment interface (IAI), is one of the parameters for analyzing the fabrication quality of the connections. The aim of this in vitro study is to evaluate

EXPLORING THE USE OF PULSED ERBIUM LASERS TO RETRIEVE A ZIRCONIA CROWN FROM A ZIRCONIA IMPLANT ABUTMENT [PDF]

, 2020
Removal of zirconia crowns, commonly used as cement-retained implant fixed restorations, can be challenging. Conventional methods of crown removal are time consuming and often leave irreparable damage to the crown, which can be costly to patients and ...

Comparative analysis of internal and external-hex crown connection systems - a finite element study [PDF]

, 2006
The abutment connection with the crown is fundamental to the structural stability of the implant system and to the prevention of mechanical exertion that can compromise the success of the implant treatment.

Double‐vestibular incision subperiosteal tunnel access (double‐VISTA) with connective tissue graft for treating multiple gingival recessions: 2‐year follow‐up

Clinical Advances in Periodontics, EarlyView.
Abstract Background Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non‐carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics.

Challenges of Soft Tissue Integration Around Dental Implants and Strategies Based on Material Surface Modification

Advanced Materials Interfaces
The stability and long‐term survival of dental implants depend not only on osseointegration, but also on complete and rigid soft tissue integration (STI) in the transgingival area.
