A CLEAR SOLUTION

Worried about being seen wearing ugly dental braces? Invisalign is a clear alternative that frees you from the emotional strain of chunky traditional braces.

Those suffering from crooked teeth have little to smile about, for fear of being gawked at should they expose their teeth. However, faced with thoughts of embarrassment and discomforts of wearing traditional braces, many put off seeking treatment.

New developments in orthodontic technology, invisalign, a treatment utilizing specially developed polyurethane aligners that help straighten teeth whilst still remaining unnoticeable.

Invisalign straightens your teeth in a comfortable and inconspicuous manner by using a series of clear, removable aligners. The course of treatment involves changing aligners approximately every two weeks, moving your teeth into straighter positions step by step, until you have a more beautiful smile. It can be removed while you eat and brush your teeth as usual.

It is an ultra-thin and smooth texture but rigid transparent aligners encase the teeth and guide them into proper alignment.

The total set of aligners needed for an entire treatment ranges from 10 to 52, corresponding to the 20 weeks and two-year treatment time required.

Candidates for invisalign: 

·       Mild to moderate crowdings

·       Spacings at the front of the mouth

·       Front teeth not touching

·       Anterior cross bite

·       Supplement to lingual braces (braces attached to the tongue-side of the teeth instead of front) in more complicated cases

Users do not have to feel overly self-conscious about their dental treatment, and can break into a smile without worrying about their braces getting all the attention.

手术性拔牙，我应该要注意什么？

1. 纱布应咬一小时，帮助止血。
2. 24小时内，应将口水吞下，不可将口水吐出，甚至做出漱口动作。由于吐口水会在口内产生负压，容易造成伤口流血不止。
3. 手术后两天，尽量避免热烫或刺激性食物。
4. 为减轻肿胀，手术后应立即冰敷，手术后24小时内的冰敷皆可减轻肿胀与止痛。
5. 手术区附近脸部与颈部有时可能会出现瘀斑，不用担心，一星期内会逐渐消退。
6. 手术后一星期内禁止吸烟。
7. 手术后可能引发的暂时性张口困难属正常现象，请进食流质性食物并加强卫生。

SMOKING AND GUM

Smoking may be responsible for more than half of the cases of periodontal disease among adults in this country.

          Tobacco use reduces the delivery of oxygen and nutrient to gingival tissue, impairs body defence mechanism making smokers more susceptible to infection like periodontal disease. In addition, following periodontal treatment or any type of oral surgery, the chemicals in tobacco can slow down the healing process and make the treatment result less predictable.

As a smoker, you are more likely than non-smokers to have the following problems:-

·        Oral cancer                  

·        Bad breath

·        Stained teeth

·        Tooth loss

·        Lose of taste

·        Less success with periodontal treatment

·        Less success with dental implants

·        Gum recession

·        Mouth sores

Quitting seems to gradually erase the harmful offeets of tobacco use on periodontal health.

Smoking causes 50% of gum disease. If you smoke >20 cigarrettes a day, risk of losing your teeth is very high. For the sake of your oral health, quit smoking or smoke  < 5 cigarrettes a day.

抽烟与牙周病

吸烟是引起牙周病的促进因素之一

烟草燃烧的热和积聚的产物是局部性刺激剂，使牙龈角化增加和牙面出现棕色柏油样沉积物，促进牙菌斑和牙石量增多，易诱发或加重牙周疾病。此外，吸烟可以使口腔粘膜形成白斑，长期含着烟在上，下唇间，会使口腔的灰白斑继续受高温的刺激，而出现皲裂和溃疡。经久不愈的溃疡，也是致癌的因素之一。

专家建议，吸烟对人体有百害而无一利，应立即戒烟或尽量少抽直到彻底戒掉。此外，一般情况下，正常人每半年或一年洗一次牙即可，对于吸烟者，最好三个月左右洗一次。定期洗牙，不仅清洁了牙齿，而且牙医在洗牙的同时又为洗牙者检查了一次牙齿，也便于及时发现问题及时治疗。

饭后十分钟，刷牙黄金时间

很多上班族都有一样的困扰，明明早晚都刷了牙，牙齿却还是蛀不停，尤其现在人工作忙碌，大部分都没有时间吃完东西立刻清洁牙齿，顶多只用清水漱口，但其实漱口并无法彻底牙齿上面的牙菌斑，顶多只能清洁一些食物残渣而已。

                                                                              

一般来说，吃完食物后的十分钟是牙齿保健的关键时期，因为此时口中的pH值由6.8降到 4.5，酸性达到高峰，此时若未立即清洁牙齿，这些酸性物质就会侵蚀牙齿表面的珐琅质，形成脱钙现象，造成蛀牙。

 

清除残渣酸性物质

因此医生建议把握‘黄金十分钟’原则，吃完东西10分钟内立即刷牙，避免食物残渣在口中产生酸性物质，便能有效降低蛀牙机率。

若吃完东西后，不方便立即刷牙，建议咀嚼无糖口香糖，这样不仅不会产生热量，也不会产生导致蛀牙的酸性物质，还可以刺激唾液分泌，加强唾液流量和速率，， 有利于清除牙面酸化和糖化食物残渣，中和口中酸性，对于口腔卫生及牙齿保健来说，非常方便有效。

让孩子有个快乐的看牙时光

                 在家做好心理准备

 就诊时，最好选择孩子精神状态较佳的时候，到了牙科诊所可以先让小朋友熟悉新的环境。三岁以上孩童的父母应扮演“旁观者”的角色，使牙医与孩子直接沟通

向牙痛的童年说再见

小朋友第一次看牙的经验非常重要。家长切记不要让孩子牙痛了才来看牙医，平常就要做好定期检查（半年一次），因为在牙痛时做任何治疗都会留下痛苦的经验。当你决定带着你的心肝宝贝首次到牙科检查时，应在家与孩子事先沟通，让小朋友了解牙齿的重要性与牙科检查的意义。

 

让孩子没有牙痛的童年

每一个小孩都是父母亲的心肝宝贝，没有一个父母愿意让自己的小孩有个牙痛的童年，当牵着他的小手走进牙科诊所时，大部分是既期待又害怕。我们希望父母及小孩走出牙科诊所时，是快快乐乐、高高兴兴的笑脸，且这辈子不再害怕上牙科诊所。

 

 

家长应扮演的角色

绝对不要告诉小朋友“一点也不痛”，而应换个语气说“可能会有一点不舒服，如果合作的话就较不会不舒服”。不要做任何承诺，例如：“今天不会拔牙”、“医生今天不会打针”。

不要妨碍牙医与孩童的直接沟通。不要过分保护你的孩子，过分的保护反而让小朋友失去学习与成长的机会。要相信牙医，即使牙医对你的孩子很凶，但出发点也是好的，不要不忍心或与牙医大吵一番。 

孩童就像一张白纸，对于牙科的认识也是一片空白，然而有意无意间，父母或周遭人物一些错误意念的引导，反而造成潜在的恐惧与忧虑。
