Bonding efficacy of highly translucent zirconia and lithium disilicate glass ceramics after femtosecond laser irradiation.
Purpose: This study investigated the effects of femtosecond laser (FL) irradiation on the surface roughness and shear bond strength of high-translucency zirconia (6 mol% yttria-partially stabilized zirconia [6Y-PSZ]) and lithium disilicate (Li2SiO3) glass ceramics.
Methods: Fully sintered square-shaped specimens of 6Y-PSZ (7 groups; 20 specimens/group) and Li2SiO3 (8 groups; 20 specimens/group) were surface-treated via sandblasting (50-μm alumina sand or glass beads) or FL irradiation (20- or 40-μm dot or cross-line patterns) or using Monobond Etch & Prime (Ivoclar Vivadent AG; only for Li2SiO3 specimens). The surface roughness (arithmetic average [Sa] and developed interfacial area ratio [Sdr]) and shear bond strength after 24 h and 10,000 thermal cycles were measured and statistically analyzed.
Results: The surface roughness of both ceramics significantly increased after 40-μm cross-line FL irradiation. The Sdr also significantly increased after FL irradiation. The 20- and 40-μm cross-line laser-irradiated 6Y-PSZ samples showed the highest shear bond strength after 24 h and 10,000 thermal cycles, respectively. Li2SiO3 glass-ceramic specimens showed the highest shear bond strength after Monobond Etch & Prime treatment for both groups. The 40-μm cross-line laser-irradiated Li2SiO3 glass-ceramic specimens exhibited high shear bond strength after thermal cycling.
Conclusions: FL significantly increases the bonding efficacy of 6Y-PSZ and Li2SiO3 glass ceramics. Furthermore, Monobond Etch & Prime is effective for the surface treatment of Li2SiO3 glass ceramics. Therefore, FL can be used to effectively treat the surfaces of dental restorations in clinical settings, facilitating enhanced adhesion between the restoration and the tooth.
期刊介绍：
Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication.
Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function.
The most-targeted topics:
1) Clinical Epidemiology and Prosthodontics
2) Fixed/Removable Prosthodontics
3) Oral Implantology
4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology)
5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism)
6) Orofacial Pain and Temporomandibular Disorders (TMDs)
7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry
8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation
9) Digital Dentistry
Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions.
Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
