Short implants with sloping shoulder design and plateau-type roots have superior survival rates when compared with regular implants. The bone condition was also witnessed to be statistically significantly superior.
Introduction:Comparison of platform switched (PS), sloping shoulder, and regular implants on stress reduction in various bone densities with finite element analysis.
Materials and methods:A total of 12 three-dimensional finite element models were built to analyze the stress distribution model. Nobel Biocare 4.3 × 8 mm regular platform replace select implant with matching diameter easy abutment, Nobel Biocare 4.3 × 8 mm replace select implant PS with 3.5 mm diameter easy abutment, Bicon 4 × 8 mm implant with 4 mm diameter sloping shoulder abutments were created virtually in compact bone density using software. The 130 N axial force and a 90 N oblique loading force were applied to the abutment to analyze the stress.Results: Under horizontal and vertical loading, the sloping shoulder implant had lesser stresses in cancellous bone when compared with PS and regular implants. Sloping shoulder implant showed more stress distribution at implant-abutment interface and at crestal area, whereas with regular implants, the stresses were distributed at cortical area.
Conclusion:Sloping shoulder implant in subcrestal position is much favorable for bone growth, stress distribution, and preservation of remaining bone.

Introduction: Effective teaching is critical for student learning, especially in professional field, such as dentistry. To cope with the dynamic state of society, the changing pattern of diseases, a clear understanding of the links between basic sciences, technology, and health care systems are crucial. Future health care provider's education system should encourage the development of learning characteristics, such as critical thinking and problem-solving. Problem-based learning (PBL) is one such method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
