A Recent Welding Technique: Laser Welding

Abstract

Welding is a process that joins two adjacent metal surfaces with or without using filling material. The latest laser welding technique is a technology based on using infrared light spectrum. Laser welding has numerous advantages considering other conventional welding options used in dentistry and because of these reasons laser welding is used widely. When searching the literature in concern with laser welding, it is observed that this technique is compared with other conventional welding methods basicly about mechanical strength and cytotoxicity. The aim of the present review is respectively to mention history, description, advantages, usage and literature studies regarding orthodontics of the laser welding which is a recent technique.

Güncel Lehimleme Tekniği: Lazer Lehimleme

Abstract

Lehimleme; iki komşu metal yüzeyin ara doldurucu materyal kullanılarak veya kullanılmadan birleştirilme işlemidir. En güncel teknik olan lazer ile lehimleme kızıl ötesi ışık spektrumunun kullanımına dayalı bir teknolojidir. Lazer lehimleme, diş hekimliğinde kullanılan diğer geleneksel lehimleme seçeneklerine göre çok sayıda avantaja sahiptir ve bu nedenlerden ötürü yaygın bir şekilde kullanılmaktadır. Lazer lehimleme ile ilgili olarak literatür taraması yapıldığında bu tekniğin temel olarak mekanik dayanıklılık ve sitotoksisite açısından diğer konvansiyonel lehimleme metodlarıyla karşılaştırıldığı görülmektedir. Bu derlemenin amacı; güncel bir teknik olan lazer lehimlemenin sırasıyla tarihçesi, tanımı, avantajları, kullanım şekli ve ortodontide kullanım alanıyla ilgili literatür çalışmalarına değinmektir.
