Adhesive cementation of the alloy to the tooth structure allows the
casting to be supported by abutment teeth. لاصق التدعيم من سبيكه الى سن
البنية تسمح الصب الى ان تدعمها محاذاه اسنان.
Has been used successfully for over 20 years for both anterior and
posterior prostheses. وقد استخدم بنجاح لأكثر من 20 سنة لكلا امامي
والمءخره الاصطناعيه.
Does not extend into labial or buccal surfaces, and pontic can be
custom stained, assuring excellent esthetics. لا تمتد الى شفوي او
buccal السطوح ، وpontic يمكن العرف stained ، مؤكدين الممتاز الجماليات.

Maryland Bridge جسر ميريلاند
in place. في مكان.
For many years, dentists had to reduce healthy teeth as abutments for
fixed bridges. لسنوات عديدة ، وكان طبيب أسنان سليمة للحد من أسنانه كما
دعائم ثابتة للجسور. Now, with the Maryland Bridge, an
ultra-conservative treatment option is available that enables the
dental practitioner to splint or replace missing teeth esthetically,
with an absolute minimum of supragingival tooth modification. الآن ، مع
جسر ميريلاند ، واحد غلاه المحافظين العلاج الخيار المتاح هو ان تمكن طبيب
الاسنان ليحل محل الشظيه او فقدان اسنان جماليا ، مع حد ادنى مطلق
supragingival السن تعديل. Combining a microfilled-composite resin
cemented to acid etched enamel and an electolytically acid etched or
silicoated cast ****l framework, the Maryland Bridge improves the bond
strength of the restoration three-fold over earlier perforated
resin-bonded retainers. تجمع microfilled - الراتنج المركب المسمنت الى
حمض etched المينا وelectolytically حمض etched او silicoated يلقي الإطار
المعدني ، ميريلاند جسر يحسن القوام السندات من استعادة اكثر من ثلاثة
اضعاف في وقت سابق مثقب الراتنج - الرهينه الخدم.
Current second-generation designs and tooth preparations, coupled with
improvements in cementing resins which rely on adhesive rather than an
etched ****l system, have provided even more exciting and reliable
restoration possibilities. الحالية الجيل الثاني من تصاميم السن
والاستعدادات ، مقرونا تحسينات في تقوية الراتنج التي تعتمد على الصمغ
بدلا من وجود نظام etched المعدن ، وفرت حتى اكثر اثارة وموثوقه استعادة
الامكانيات. Adhesive cementation of the alloy to the tooth structure
allows the casting to be supported by abutment teeth. لاصق التدعيم من
سبيكه الى سن البنية تسمح الصب الى ان تدعمها محاذاه اسنان. Bonding also
prevents displacement back along the path of insertion. الضمان يمنع
ايضا من النزوح الى الوراء على طول الطريق من الادراج. Because
displacement of the casting in all directions other than along the path
of insertion is prevented by alloy engaging tooth structure, the
framework design limits the stresses placed on the luting agent and
bond, dramatically increasing the longevity of the restoration. بسبب
النزوح من السبك في كل الاتجاهات الاخرى من الطريق المؤدي الى ادخال امر
بها حالت دون اشراك سبيكه هيكل السن ، في اطار التصميم يحد تشدد على
التطيين الوكيل والسندات ، وزيادة هاءله في طول استعادة.
Ultra Conservative Preparation غلاه المحافظين إعداد
With the Maryland Bridge, fixed partial dentures, periodontal splints
and a variety of other conservative restorations can be placed with a
minimum of tooth modification. مع جسر ميريلاند ، اطقم الاسنان الجزءيه
ثابتة ، ومحيط بالضرس الشظايا وطائفة اخرى من المحافظ الاعاده يمكن ان
توضع مع حد أدنى من سن تعديل. Abutment teeth are basically left intact -
one unit is not weakened in the process of replacing another. محاذاه
اسنان هي أساسا - دون ان تمس وحدة واحدة وليس إضعافها في عملية محل اخرى.
Modifications are restricted to rest preparations and recontouring of
the enamel is only required in severely undercut cases. وتقتصر
التعديلات على بقية الاستعدادات وrecontouring من المينا هو المطلوب فقط
في حالات ضربة شديدة. All tooth preparations are supragingival, making
modifications kinder to the periodontal tissues and impressions easier
to obtain. ألسن جميع الاستعدادات تجري supragingival ، مما يجعل من
التعديلات ارحم الى محيط بالضرس الانسجه واسهل للحصول على الانطباعات. By
avoiding preparations involving dentin, sensitivity is virtually
eliminated either from the preparation or subsequent cementation
procedure. عن طريق تجنب الاعمال التحضيريه التي تنطوي على dentin ،
الحساسيه هو القضاء فعليا اما من اعداد أو تدعيم الاجراءات اللاحقه. Most
importantly, as the Maryland Bridge requires little or no removal of
tooth structure, the treatment is often reversible. والأهم من ذلك ،
وكما جسر ميريلاند تتطلب القليل او لا ازالة السن الهيكل ، والعلاج هو في
كثير من الاحيان للانتكاس.
Superb Esthetic Result جمالي رائع ونتيجة
Labial ****l collars create difficult esthetic problems when the
patient has a high lip or smile line, a problem that is compounded
where the gingival tissues are thin and fragile. شفوي معدن الياقات خلق

margins are only a temporary solution as the gingival tissues will

الهوامش سوى حل مؤقت كما gingival الانسجه سوف تنحسر مع مرور الزمن ترك
