“…43 Although, the adverse effects of covering the teeth with a lingual plate were described already in the last decades, it is still a common major connector type in many dental practices. 44,45 According to the above described disadvantages the use of a lingual plate does not improve oral health. On the contrary, it has several adverse effects and it can be regarded as a treatment failure.…”

Aim: Although there is evidence that covering teeth by parts of a denture may damage teeth and the periodontium, the lingual plate is still common in clinical practice in many countries. The aim of this study was to compare the lingual plate and lingual bar type major connectors in the lower jaw as reflected in the literature. Materials and methods: A literature search was carried out in PubMed for articles focusing on the possible effects of lingual plate major connector on the oral environment. Case and technical reports were excluded. Results: The lingual plate which covers the soft tissues of the periodontium and the hard tissues of teeth results in increased plaque accumulation, development of caries and gingivitis, which in turn results in periodontal breakdown. The lingual plate functions as a barrier to saliva circulation, decreasing selfcleaning of teeth on the covered surfaces. Wearing a linguoplate denture increases the likelihood of halitosis, corrosion and metallic taste. Patients have to wear a large volume of metal, which may cause difficulties in speech and may impair touch and form perception. The lingual plate may not satisfy the patient's esthetic expectations either. These issues are uncharacteristic for the use of lingual bar connector for removable partial denture. Conclusion: A lingual bar should always be used in the lower removable partial denture, thus providing a hygienic denture design, comfort and esthetic appearance.

“…Anvendelsen af titanium eller titaniumlegeringer i delproteser er begraenset, men anvendes bl.a. på patienter med kontaktallergier mod kobolt, palladium og guld (46). De støbelegeringer, som i dag hovedsagelig anvendes i stel til delproteser, er Co-Cr-legeringer og CP titanium eller titaniumlegeringer, og vi skal nu se naermere på deres egenskaber.…”

Selective and noncontaminated surface polishing of titanium alloy implants is crucial in the biomedical field. We employed a pulsed laser as a localized and selective heat source and dilute phosphoric acid as a corrosion solution for laser chemical polishing (LCP) of medical Ti-6Al-4V titanium alloy surface. The effect of laser fluence on the removal groove morphology of titanium alloy surfaces was systematically studied, and the characteristics and mechanisms of material removal were further discussed. The results show that the groove morphology of the workpiece surface at different laser fluences can be classified into three categories, depending on the two-dimensional removal profile. The removal mechanism of LCP is a combination of laser etching and chemical corrosion, and chemical etching can completely remove the residues and melts produced by laser ablation. Finally, selective polishing of medical Ti-6Al-4V titanium alloy was achieved by setting appropriate process parameters. Moreover, the energy-dispersive x-ray spectroscopy analysis showed that there was no detectable chemical impurity contamination on the polished surface.

Titanium alloy removable partial denture framework in a patient with a metal allergy: a case study

Abstract: Diagnosis was of a non-retentive, unsupportive mandibular distal extension RPD, with bone resorption leading to a prominent mylohyoid ridge resulting in trauma to the overlying mucosa. Moderate chronic generalised periodontitis exacerbated by chronic smoking was also present.
