(A) Taper-point needle. ETHICON Suture Needles Carefully selecting a surgical suture needle is a critical component in achieving excellent wound closure outcomes. Tapered needle points are used when minimal effort is required to penetrate the tissues as they produce the smallest holes. Type II – Cotton or linen fibers or coated natural or synthetic fibers in which the coating contributes to suture diameter without adding strength. Classification of sutures based on suture size. Straight (limited use in oral surgery) or curved . The process of degradation depends on the material and range from ten days to eight weeks. Suture sizes are defined by the United States Pharmacopeia (U.S.P.). Suture materials can also be sub-classified by their structure: Monofilament suture – a single stranded filament suture (e.g nylon, PDS*, or prolene).
