Currently, there are many implants in clinical use, making it hard to choose the right one for the patient. The success rate of an implant depends on its diameter, length, and direction of insertion in bone. In implant dentistry, Finite Element Analysis (FEA) simulates intraoral conditions in vitro and analyzes the effects of implant material, diameter, size, and other components related to oral structure on the implant and peri-implant tissues. The objective of the present systematic review was to evaluate the influence of variation in Dental Implant dimensions on Peri-implant Bone Stress/strain distribution, where Finite Element Analysis (FEA) is used as a method of analysis. ⋯ The evidence from the most recent literature suggests that the use of FEA showed promising results in understanding the stress distribution surrounding the implant. It was discovered that the material of the dental implant and the prosthesis, the type of loading, the direction and magnitude of force (axial or non-axial), the quality and quantity of the bone that surrounds the implant, as well as other factors, all play a role in the maintenance of bone around dental implants.

The objective of the study was to assess whether the measurement of the angle of progression in nulliparous women in labour can predict the mode of delivery. ⋯ The angle of progression is a reliable tool for predicting the mode of delivery. Wider angle is associated with vaginal delivery and a narrower angle is associated with cesarean section.

This study aimed to investigate the relationship between oxidative stress (OS) and endometrial polyps (EP) in pre- versus postmenopausal women with abnormal uterine bleeding. ⋯ Serum OS may play a role in the development of EP, particularly among postmenopausal women. Further investigations are required in this area.

To explore the radiological findings of neurological disorders in obstetrics patients, their obstetric and fetal outcome. ⋯ Pregnancy-related neurological problems should be taken carefully and evaluated, since even seemingly insignificant symptoms like headaches may be signs of serious illnesses like PRES or DST.
