Restoration of Two Implants using Custom Abutments and Transverse Screw-retained Zirconia Crowns

Jul 23. 2021

The American Journal of Esthetic Dentistry featured Yugo’s article titled 'Restorations of Two Implants using Custom Abutments and Transverse Screw-retained Zirconia Crowns' co-authored with Dr Andrew Chio (Melbourne, Australia) in 2012 (originally published in English).   There is a myth that the popularity of cross-pin retained implant restorations exists in a specific geographical location – Melbourne, Australia. Cross-pinning uses a transverse screw to attach the restorations to an implant abutment when access for the abutment screw would compromise the aesthetics and structural integrity of the prosthesis.   This technique traditionally requires the final restoration to be completed as an all-metal or metal-ceramic prosthesis. However, this article explores the possibility to fabricate the restorations using metal-free Zirconia based systems. This case report presents an alternative technique...

Ultimate Zirconia Coping Design: Understnding Aesthetics and Function

May 07. 2021

eLABORATE Magazine featured Yugo’s article titled ‘Ultimate Zirconia Coping Design: Understanding Aesthetics and Function’ in Sep/Oct 2012 (published language: English).   Introduction: It has been a decade since Zirconia became available to the dental market, and it is now one of the premier alternatives to Porcelain Fused to Metal (PFM) restorations.   There are always pros and cons in selecting any material, and dental professionals need to treat their chosen material properly to ensure the longevity of the restorations. One of the common issues facing Zirconia is the potential fracture of the layering ceramic/porcelain (Fig 1 & 2). The general causes of the problem are: Firing program/conditions, Parafunctional stresses, Ceramic-Zirconia compatibility, and Insufficient support in the sub-structure.   Understanding of function/occlusion, visualisation of the outcome and an appropriate...

Unbreakable Zirconia Abutments: New Lava and NeoLink Zirconia Abutments

Mar 26. 2021

eLABORATE Magazine featured Yugo’s article titled ‘Unbreakable Zirconia Abutments: New Lava and NeoLink Zirconia Abutments’ in Jan/Feb 2010 (published language: English).   Introduction:   Strength and aesthetics are foremost in the mind of today’s ceramist. The longevity of restorations has always been an essential factor. In the past, however, aesthetic compromises may have been tolerated, particularly in the posterior region. Thankfully today, achieving a lasting, highly aesthetic result technically has become far more accessible due to the development of new technology and materials. In the burgeoning field of implant dentistry, to maximise aesthetics, it is essential to create a customised abutment instead of using ‘off the shelf’ abutments. Custom abutments are necessary to control the emergence profile, as well as the Sub-Gingival Contour (SGC). Customised Zirconia...

Before and After 2012: Smile Makeover – Achieving Significant Change in Proportion with porcelain veneers

Feb 05. 2021

A Caucasian male patient in his 30s was deeply concerned about the aesthetics of his smile. There are several issues we had to address: most notably, changing the proportion and tooth size within the aesthetic zone, crown-lengthening/gum-contouring, and a replacement of a missing tooth on 14 (right first-premolar).   We selected a Zirconia bridge on 15-13, and lithium disilicate (e.max) veneers for the rest – 12-26 (missing 25), from the right second-premolar to the left first-molar, a total of 10 units.   I must admit that this case was one of the most challenging smile makeovers I had encountered at that time, but the result spoke for itself. The patient was “over the moon” with the outcome.   The key to achieving such a result was...

Before and After 2010: Treatment of Cleft Lip and Palate – a “Pro-bono” Smile Makeover

Jan 08. 2021

A female patient in her early 20s presented with congenitally missing upper lateral incisors, and one canine, a total of 3 teeth seeking a fixed replacement. The patient has a cleft lip and palate bilaterally, which has been treated several times over the years with surgery to repair it. Implants are not possible as there is no bone in the surgical repair sites, and in fact, she still has an oro-nasal communication.   The patient had limited resources to pay for treatment and hoped that the federal Cleft Lip and Palate Scheme would cover the costs, which turned out that only extractions and dentures are eligible for the claim. Thus, the treating clinician – Dr Michael Mandikos and I had decided to treat...

Reproducing Nature Part 2: Blending into Natural Dentition

Jan 01. 2021

eLABORATE Magazine featured Yugo’s article titled ‘Reproducing Nature Part 2: Blending into natural dentition’ in May/June 2006 (published language: English).     Introduction:   Isn’t colour matching a restoration to nature one of the hardest things for all of us to achieve? To be able to reproduce the colour, there are so many factors we have to consider and get right. The value, chroma, hue, translucency, characterisation and even the surface anatomy and shine control of the tooth are all essential considerations.   However, from my perspective as a ceramist, we have to consider another crucial aspect – the background. The teeth in the mouth are always under the influence of the colour from the gum, and it is very easy for human eyes to make misjudgements...

Before and After 2008: Welcoming my Inaugural Patient at Smile by Yugo

Jan 01. 2021

A Caucasian male in his 30s presented with a trauma case on the (patient’s) right central incisor (11) – had an accident while playing football. He was also concerned about the appearance of the (patient’s) right lateral incisor (12) – it appears too short and narrow in his words.   11 is a non-vital tooth with minor discolouration in the stump (c.f., Fig 1); thus, we selected a zirconia restoration. The opacity of Lava Zirconia was suitable for slight masking, and its aesthetic advantage in complex colour matching.   12 is a healthy, vital tooth clinically speaking (c.f., Fig 1), thus we required only a minor conservative prep to proceed with the refractory veneer. Additionally, bleaching was completed two weeks before the shade taking...
