# Laser Mechanized Physicochemical Characterizations on the Surface of Implants and Dental Abutments

## TL;DR

This study examines the surface characteristics of Laser-Lok dental implants to assess their physical and chemical properties for better integration with bone and tissue.

## Contribution

The paper provides a detailed physicochemical characterization of Laser-Lok implants using microscopy and spectroscopy techniques.

## Key findings

- Microgaps in the implant-abutment joint ranged from 0.5 μm to 5.6 μm.
- Defects were observed on the implant surfaces that could affect microgap size after connection.
- Laser-Lok implants show favorable macro and microstructures for primary stability and cellular organization.

## Abstract

Introduction

Dental implants have revolutionized dentistry, offering effective solutions for the rehabilitation of masticatory function and dental esthetics. BioHorizons Laser-Lok dental implants are known for their innovative surface, which uses laser technology to create microstructures in titanium, improving interaction with bone and periodontal tissue.

Objective

To evaluate the microscopic physical characteristics and elemental composition of titanium implants grade V.

Material and method

This descriptive and observational study evaluated physicochemically grade 5 purity titanium implants: Tapered (BioHorizons) Bone level Laser-Lok resorbable blast textured (RBT) titanium implant by scanning electron microscopy and energy dispersive spectroscopy. The sample analyzed consisted of a single implant unit corresponding to the aforementioned model. The samples were subjected to microscopic analysis for topography. The microgrooves of the implant neck and the frontal view were analyzed for microphotography and proceeded to their physical description.

Results

Defects were observed in different areas of the tooth abutment surfaces. The minimum and maximum size of the microgaps ranged from 0.5 μm to 5.6 μm. In addition, defects were detected throughout the implant-abutment joint that may ultimately affect the size of the microgap after connection. Conclusion. Laser-Lok biohorizons implants present an ideal macrostructure and microstructure for the placement process and primary stability, favoring biomechanics. In addition, due to their specific organization and reduced distance between the grooves, they allow adequate cellular organization and differentiation.
