Modified implant placement guide ( Original Research Article)

Abstract

Mini-implants or mini-screws also known as Temporary anchorage devices (TADs) have become widely accepted component of everyday orthodontic practice as chief anchorage source. The proximity of the implant to the root surface, placement in the alveolar mucosa and improper angulations are the most important reasons for failure of mini-implants. So we have designed a modified implant placement grid which does not need to be attached separately to a section of wire; as it can be fixed easily to the Final archwire with the help of Guerin lock. This guide can be used in buccal as well as lingual cases. The grid is approximately 2.5 cm in height and the overall structure is rectangular in shape with 10mm in length and 5mm in width and also has an extending long arm which is approximately 1.5mm in length. With the use of the custom made modified grid, the implant can be precisely and dependably placed in areas of reduced space and near to important anatomical structures. The versatility of the grid lies in the fact that it can be fabricated chair side and suits in different anatomic location and clinical situation.
